Sold out.
The RG34 (Reinigungsgerät 34) was issued to every soldier of all branches of the Wehrmacht, and was a universal kit for the majority of small arms (from 7.92mm to 9mm). This meant that one kit was used for pistols, rifles machine pistols and MGs.
This is the post-war version, which is virtually identical to the war-time issue (except for one tool).
