Sauer 38H Very early model
I recently purchased a Sauer 38H, with Serial Number 2666XX. It has NO eagle acceptance marks, but does have the thumb safety. The back of the rear sight is also painted the same red as the safety dot
This would seem to refute that the early ones did not have the safety. The Wehrmacht serials start at 271xxx, and the production of the model 38H started with about 260,000, as I understand it.
