I inherited an old 16 gauge side by side a few years back from my grandad when he passed. I was never told about the gun prior to his passing, my mom vaguely remembers the gun being in her grandmothers house when she was growing up. It is very ornate, appears to be German. With the only writing on the gun being in the barrel reading Robert Michel Muhlhausen I/TH. Trying to place when and where the gun came from. Any information will be greatly appreciated.
