Eye and Trefoils

In use for Classes:

• 15

This decal is sometimes called also "Triplets".
Commonly used on 15-class machines.

We recorded also a couple 66-class with these decals, but it could be a later application of decals on an older machine. Those 66 models were 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.
