Based on information found in the database maintained by my friend and collaborator, Charlie ("ordnanceguy" on the forum), and me, the five-digit SN V-34,8xx should have shipped in mid-1942, most probably July of that year.
You don't stipulate the condition of the gun, but the price paid sounds real good to me.
In order for us to include your gun in the database, we need the full SN and details on any martial markings, if any. If you would like to contribute, you may post the info here or e-mail me off-list at
[email protected] (removing the "NOSPAM," of course).
