Dilly141,
The proof dates were stamped by the proof house, not the manufacturer. The likely reason your Sauers are dated and the T&S is not is because the Suhl proof house started dating them around 1923. The T&S likely went through before then and the Sauers were likely later. This can be confusing because the Zella-Mehlis proof house started dating them much earlier than Suhl and also marked the ledger number.

Thats great info. Thanks again.
Do you happen to know anything more about the firm? I read a bit about them in Norbert Klups book and it seems they had a solid reputation for building quality drillings. The action is remarkable in that it seems so simple.
