One of the latest entries into MiniArt Models line of WWII Military Miniatures is a German Machine Guns set. There is enough styrene in the box to build two MG 34's, two MG 42's and one ZB 53.
The ZB 53 was a Czech design and were from captured stocks after the German Army invaded Czechoslovakia at the beginning of WWII. The Germans later changed the designation to MG 37. All of these weapons utilized 7.92x57 ammunition. Fun Fact: The MG 42, although redesigned and improved, is still in service as the MG 3.
Along with the machine guns there are parts for ammo cans, barrel canisters, and ammunition belts. MiniArt thoughtfully includes photoetch bits for the carrying straps/slings of each gun, handles for the ammo cans, and the cooling vanes/heat shields on the barrel of the ZB 53. All in all, you get 84 pieces of plastic and 38 photoetch bits. I found assembling those slings fiddly but on reflection a better in scale method eludes this author.
