Looking for some information on a M1 carbine marked G.H.D. on receiver.

[Mike Haas]

Just to refresh your memory here is the old thread from the CMP forum. CMP Discussion Forum - Underwood carbine marked as G.H.D. ?
Unfortunately the old threads from the former CSP forum are gone so can't provide a link to that thread. All three threads are of the same carbine with the same pictures, although this time there isn't a picture of the soldered on TH lug, and all the threads were started by someone with the same name.
