Thanks.
Erfurt plates require more input.
Neither George nor I said Erfurt plates had numbers inside.

I have not found any similar numbers on the few matching Erfurt pistols I have; an occasional letter or number yes, but no "pattern" of use. The one Simson plate I have has no number inside either.

My preliminary conclusion is that Erfurt did Not number plates on the inside.

This may be logical, as Erfurt production volume was only 1/2 or so of DWM production and thus it may not have been an issue for them; or their batch process was designed around finishing less than 100 plates per lot.
