fuhrmann: thanks for following along and providing input. Lovely find and it piques Baumgarten's and my interest in the source of the Muzzelverschluß as well as being chambered in 9.3X74R. Here it would seem that W. Foerster sourced H. Barella who in turn sourced one or all of the Merkel Boys. H. Barella and the Boys Merkel had strong sourcing ties. H. Barella acquired other concerns and might have had a stake in W. Foerster? It may be that a pinned receiver was a condition for W. Foerster's wares. Like you, I too think the side plates and selector was a later addition to the 9.3X74R Muzzelverschluß. The frame at least experienced proof twice with the 1st pass looking to be in 1925. As stated a later pass may have been in 1934. Very unique Hubertus Cross on the underside of the muzzle.
Kind Regards,
Raimey
