I don't know enough about Imperials to contribute much to this thread. But, doesn't the barrel look like .30 Luger? I counted the coils in my Portuguese 1906 pattern chambered in .30 Luger, and it has 15 coils on the mainspring which is about what I count here. The Portuguese shoots perfectly and looks fine on the tape test (mainspring is OK). So I'm thinking he's OK to shoot this if .30 Luger?
