There is another set of numbers on the rib ahead of the forearm hook 7136.12.15'8. 8'4 I have used the apostrophy for their raised decimal point (assuming that is what it is). It is a hammer gun. I thought the 12.1 gM.G. following the 9.3x72 meant 12.1 gram metal jacket bullet as the service load.

Thanks Raimey.
