Folding ruler ID

[BoTown]

Hi, looking to ID this folding ruler. The only identifying mark is “No. 11.” That and the hinge design makes me think it’s a Stanley, but I can’t find any other markings on it. Could it be some kind of Stanley knockoff from around the same time?

Thanks

Well, according to the reference book Boxwood and Ivory, Stanley never made a #11, so that takes them off the table.

Other manufacturers weren't necessarily knock offs, some were innovators, and that is why Stanley often bought them.

But back to your #11. H. Chapin's Son in the 1890 catalog, lists a #11 as Square Joint, Middle Plated, 8ths & 16ths, in a two foot, four fold, narrow rule, at 1" wide, for $5/doz.

Those bold words in the middle are the tough part, but yours matches those. This is a mid range rule, the arch joint and edge plate is the high end. I'm trying to post a link to a catalog showing the words, but its not loading right now.

This link, go to page 7, for a description of the joints and plates.

This is awesome info. Thanks much! I’ll dig a little more into Chapin rules.

Feel really lucky to have found these two today.

Chapin & Stephens #65 Folding Two Foot Rule
H. Chapin #85 Ship Carpenters' Bevel, Double Tongue (smaller tongue is stuck unfortunately)

Curious on the age of the #85 as it is marked "H. Chapin US Standard" which I assume is much older.
