I note the 87 has a “5” plus same sn style & orientation as mine on front plate. Gary’s illustrations are bringing us close, but the EP designation would’ve come almost a decade later. Possible the layouts changed and/or size (we’ve noted size changes before)

It is speculation, but this may have bearing on the mystery mark seen on the 839. A stylized L & J mark? I am wondering if he is our ebauche supplier to Favre (& Ditisheim) for the EP movements I’ve assumed were Favre, some being reverse engineered into in house Favre calibers ca1920. There’s a lot here to decipher. Thanks to all you real researchers—my brain is exploding! 🤯

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