1918 DWM military

[campfooey]

I have a Po8 DWM 1918 military. It has all the military proofs and matching numbers but scribed with a electric marker are some small numbers on the barrel and receiver looks to be F9 - 14498. There are the standard military proofs on right side of receiver but one extra one a back to back F v shape with small letters under it [ H7aJL3 ] hard to read though. the back to back V shaped F is also on the barrel twice one next to the serial number and one upside serial no. 3121 a barrel 3121 8,82 and a 42 under that . its in good shape most of the bluing is there no pitting and good bore. There is a extra barrel align mark. any ideas of what I inherited from my uncle. john jsteffs@yahoo.com
