Howdy Liz! Thanks for the feedback--would appreciate your help descrambling these, so I can correct the post & can learn (even Dr. Ranfft is uncertain). No, mine isn't stamped on the movement, but then again I wouldn't expect it to be stamped until 1921/1922. I had closely studied your older post (101 vs. 626), as well as the 101 shown in the 1926 parts manual. I don't have supplement b, I'm afraid. Thanks for sharing the example of your stamped 101--would love to see a definitive image of 626.

Putting them all side by side with mine at center: the left from 1917; the middle 1917-1919 (I propose 1917); the right from 1923. First, seeing them this way now, I have to say if there's any sign of an old vs. new 101 style, your two seem the closest (both with a cutaway, bent finger bridge, bridge going over the top middle jewel vs. bubble, marked Gruen W. Co). Mine's the odd man out--so good candidate for 626. Your stamped one matches the 101 image in the 1926 parts manual, which is stamped for pre-1923 and is a redesigned bridge + new setting mechanism in any case, as old version parts are shown. I noticed the slight variance in screw locations where I've circled, as well as the 101 dial stamp. The movements came to the US already with dials on them, although if they were the same size/layout & from same factory they could use one number/dial for either.

Now I'm more wondering if you've got two 101s and I've got the 626. What was stamped on your dial for the one at left? Was it 626?

My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
