Here's an ad snippet for Minute Man "B", and a second ad from 1939 or right.

There's a 1939 Minute Man example here, with the following crystal specs and case deminsions listed in root record:
Crystal Details:
Federal: MT4-265 165
Additional Information:
Case measures 42.5mm lug to lug x 22mm wide non inclusive of the Crown using Calipers.
I'm good with a Minute Man ID, would give two ticks for tentative.
Katrine, case demensions of subject watch will help.
...and with two similar examples Bobbee listed/displayed above, it could be the emblishments were not added aferwords... The other similar example doesn't have case demensions listed either.
