The fourth marking on this AC 40 added
is an eagle over Hza Jt3. On Third Reich small arms the marking means a depot
level rework. This gun has seen battle! Most parts replacement was done some level
below the depot (ie: the unit) Depot level work is usually reserved for a major
overhaul or repair. This gun has had the barrel (and perhaps other parts) replaced
since the serial number is missing the letter designator on the barrel and block.
The abbreviation is for the Heereszeugamt
organization that performed the repair to the gun then the Instandsetzungwerkstätte
(Repair Work Shop) and the number of the shop. The capital letter "J"
was often used to represent the letter "I".
The marking is extremely rare for
P38's as Buxtom has only two reported, one is pictured on page 271 of vol. 1.
