Original Item with WW2 German Markings:
The LS42 is noticeably shorter than the Laufschützer 34. It was soon replace by the Laufschützer 43 "dual purpose" carrier and is the least common of German WW2 barrel carriers.
These came out of Yugoslav arsenals and were typically repainted after WW2. Slings may be post war as well
Original German marked Laufschützer 42s are quite rare since they were quickly replace by the Laufschützer 43 (dual purpose) barrel carrier which worked with both MG34 & MG42 barrels.
