Yep,they've found a new home in my gun room..... from what I can find out the Amberg sporters are somewhat scarce, with probably only a few hundred made, if that. Mine is S/N 161 and the one on AA is 114. I got that and a C. E. Heinzelman that is marked S. Heim Nurnberg posted below. All I can find out they were in business from 1921-1928. I'm hoping someone has more info. on Heinzelman/Heim.
You're right the other one is somewhat disagreeable. Mine hasn't been messed with and several hundred $$$$$ less......someone should have been whipped for the extra embellishment on the the forearm and for wielding a drill.....or at least given better instruction. :-)
