The sewing machines produced in the Singer factory in Monza (Italy)

Latest update on 1 month ago

I’ve been working for a while now on a searchable database of Singer sewing machine serial numbers. You type in a number, and it tells you the extant information on your machine: when and where it was made, which model it is, and – when I can find them – even manuals and other useful info.

One thing I’ve grown more and more curious about is the story of Singer machines made in Monza, Italy. Being Italian myself, I naturally felt drawn to learning more about the production that took place there. But there’s surprisingly little information available, compared to other Singer factories. Which models were made in Monza? When exactly? And how can we identify them today?

So, I’m starting a dedicated research project focused entirely on Singer machines made in Monza. My goal is to collect as many serial numbers with their model numbers as possible, and try to narrow down the production dates based on what we find. Eventually, I hope to build a complete list of what was made there and when.

If you own a Singer machine that was made in Monza (or even just suspect it might be) please consider sharing the details in the comments, with as much information as you can. Serial number, model, any markings or labels, even a photo if you’re willing. Every piece helps!

Let’s build this puzzle together.

MA013633	15M	1934-1992
MA027373	15M89	1934-1992	Decals: Eye and Trefoils.
MA038602	411M	1934-1964	Model 411M in its original Italian cabinet. The cabinet has a label with testing date on 10th January 1964. When the cabinet is original, labels like this (usually found on cabinets for Italian- and German-made 400-series machines), can help narrow down the production date of the machine itself.

Decals recorded in the factory of Monza

Here are the decal sets recorded in the factory of Monza, with their periods of use and the classes (models) they were applied to.

It’s a cross-reference of known Singer decal sets with the serial numbers in our own database. This may be helpful to date machines when serial records are incomplete.

Eye and Trapezoids

Decal

Use recorded from 1955 to 1960

Verified machines in this factory

(What does it mean?)

Total verified machines: 23

Verified Classes:

Eye and Trefoils

Decal

Use recorded from 1921 to 1954

Commonly used on 15-class machines. We recorded one 66-class with these decals, but it's probably a later application of decals on an older machine. That 66 model was manufactured two decades before the patent for the Trefoil decals was filed. We also recorded a few 24-18 machine with Eye and Trefoils decal, produced before the 1931 patent for this decoration was files. It's indeed possible the patent was filed after the set had been used in production batches. Notice that the patents, while not mentioning specific models, seem to picture class 15 machines or similar.

Verified Classes:

Godzilla Finish Logo Only

Decal

Use recorded from 1930 to 1953

The so-called "Godzilla finish" is also known as "crinkle" or "wrinkle" finish. Because of the nature of the crinkle paint, the decals are usually fainter than the more common bright golden decals. "Godzilla" models seem to have been manufactured with non-crinkle shiny drive wheels.

Decal

Similar to the Eye and Trefoils decal set, but without the trefoils. Recorded in use in the factory of Monza (Italy). Decal name recorded by us at #LRCrafts, for lack of documentation elsewhere.

Brief history of the Singer sewing machine factory in Monza

24th April 1935: minister Edmondo Rossoni officially opens Singer's factory in Monza (Italy)

La rivista Famiglia fascista Anno III num 4 aprile 1936 Anno XIV

Singer’s Italian story began in 1914 with the founding of La Compagnia Singer per Macchine da Cucire, headquartered in Milan. For twenty years, it served as the distributor of imported sewing machines.

In 1934 Singer acquired the premises of the Società Anonima Meccanica Lombarda in Monza, Via Marsala 9: it was a site already rich in industrial history, thanks to Swiss entrepreneur Alfredo Zopfi and his foundry. On April 24, 1935, amidst much fanfare and the presence of Fascist dignitaries such as the Italian agriculture minister Edmondo Rossoni, Singer officially opened its new Italian manufacturing plant.

The Monza factory became a cornerstone of the city’s working life. Entire families worked there, forming a tightly knit community. The company didn’t just offer jobs—it provided social spaces, sports activities, and a sense of belonging. Even today, locals refer to Monza’s Centro Sportivo Ambrosini as the “ex-Singer” sports center.

As production ramped up, Singer outgrew the Via Marsala site. In 1968, it relocated to a modern facility on Viale Sicilia, near the suburb of Concorezzo. At its peak, the factory employed around 1,800 people and was turning out a remarkable 17,000 machines every week. That same era saw Singer release the groundbreaking Athena 2000, in 1975: it was the world’s first electronic sewing machine, designed and built in Monza.

But challenges loomed. The Monza factory faced stiff competition from Singer’s plant in Campinas (Brazil), which produced the same models at a fraction of the cost. By 1973, Monza’s production costs were reportedly six and a half times higher. Despite efforts to modernize, the financial strain was too great, and the factory began downsizing through the 1980s.

Singer changed hands several times, including a controversial sale to the Iraqi businessman Kassim Abbas. Allegations during the Gulf War linked the company to illegal exports, and Abbas was expelled from Italy in 1991. It marked the final chapter for a company that had once been the pride of Monza.

Singer finally shut its doors in Monza in 1992.

Hi!!

I just stumbled upon a Singer 227M made in Monza at a flea market this morning! I took it home, cleaned it up, and it runs beautifully, though I can’t speak to the stitching until my new external cone holder and thread guide arrive on Monday (the thread guide and spool holder were not with the machine).

Here are all of the details that I have:

Model: 227M in a cabinet (I don’t know if it’s original)
Serial number: MB263641
Location most recently purchased: Delaware, USA
Color: Beige

I have several pictures, but I don’t see a way to add them in the comments. Please feel free to email me and I’ll send them to you!

    Sadly I do not. I sent a message to the seller asking for info on its history, though from their storefront it looks like they’re an estate liquidator or something so my expectations are low. If they reply with anything helpful I’ll pass it along.

Hi,

I purchased a Singer 237 from a New England seller on Mercari #ME502137. It works great. It also has another number stamped in the bed under the serial number 175559 maybe that’s a mold number?

  Oh thanks a million! The number you say could be a part number. Main parts were numbered to be ordered easily. Thank you again!

Hi, found this page after being curious about the Singer 237 I’ve been using, inherited by my grandmother many years ago 🙂

We lived in Belgium, so I assume she purchased it there.

Singer 237 (portable model), MD074453

Happy to send photos, just drop me a note

Hi Sara, as promised, the details of the Singer 237 that I bought here in France a few weeks ago. Her number is ME 243449. She was sold to me by the son of the lady who bought it new from a shop in Poitiers, France. Perfect condition. In a lovely cabinet with treadle and electric motor. Sews beautifully!

Olá,
Tenho uma máquina de costurar Singer, delegação de Sta. Apolonia, máquina n.MR239104, despacho 6319 do ano 1956.
Alguém me pode informar como ajustar a lançadeira?
Já aliviei os três parafusos por baixo da lançadeira mas não alivia do eixo.
Agradeço a eventual ajuda.

Sara,

Your link for more information about the 237 is broken. However, I noticed that it is a webarchive version of a still active website. Paul Fox’s website is here:

  Thanks a million! I’m going to fix it. I tend to use archived versions in the case a website expires without my notice, as happened for example for The Needlebar.

I have a Fashion Mate 257 with serial number MH189557. I purchased it from Facebook marketplace in Georgia. No known history from the seller. It is in a Singer sewing cabinet, I believe one of the model 40 styles but not sure. I cleaned it up, greased it and oiled all the movable points. It sews quietly and beautifully. It is a ZigZag sewing machine. There is a good history of the Monza factory at https://www.singersewinginfo.co.uk/history/factories/monza/

  Thanks a million for telling us about your machine.
  Unfortunately, dating Monza-made machines is tricky… no records survived. And having dates about serial numbers of the same series is not always of help. We recorded serials lower than yours at the beginning of the 1950s, so having a photo of your machine could help: if your machine has the so-called “Centennial Badge”, its production period could be narrowed to 1949 – 1952, since Singer used that kind of logo badge in the years around its centenary of activity. If you want, you can write to us via the About Us page and send a photo. Thank you again!

I bought a 506M some years ago, with user manual, accessories and some useful spares.
It comes with it’s wooden cabinet, dust and rust.
Then I only cleaned and polished the exterior, today I’ve done a complete check and try on. High quality materials and engineering in a black body S/N MB402991.
I’m from Italy.
