Gnter:
I wasn't going to say it but keep posting until you took note. We must be on the same wavelength or my efforts are most revealing. I might go as far as to invoke happenstance, but that's about it. The following Carl Grndig peddled drilling from December 1929 looks to have the same marks as well as the EHk as seen on Baumgarten's bunny dispatcher retailed by W. Eblen,

along with what looks to be Wilhlem Kelber's stamp lower, closer to the lugs. With the Kelber marks, I wonder how much effort was devoted to the scattergun tubes? But it does seem that the marriage of these mechanics marks originates at E. Schmidt & Habermann, which Emil Stadelmann may have owned prior to Gebrder Stadelmann.

Proofed in the final state, Carl Grndig waffenhndler.
