I brought home a couple more long-C screwdrivers yesterday, along with a wavy logo framing square. The fifteen incher is the longest one I've found. It had a lot more paint on it, but I chipped most of it off. Based on the condition of the tip, it's had a lot of odd jobs in its lifetime.
The square has two patent dates on it, so I looked those up. One from 1900 and the other from 1914.

It's in pretty good shape for its age, which may be due to the fact that it's copper plated. I keep an eye out for squares that taper in thickness, because that detail is used on the nicer examples. The thick part at the corner measures .165" and the end of the long leg is .080"; putting the strength where it's needed and saving weight where it's not.
I try to be fussy about which framing squares I bring home because they're adding up, but I did not hesitate to buy this on. I get a kick out of that logo.
