Lot includes three 7.92mm machine gun barrels (all clear, one installed in heat shield assembly), three ammo drums (two in a steel carrier), lengths of non-disintegrating metal cartridge belts (sans ammo) and assorted components and spring. About 12 starter tabs are included with the belts. A set of schematics related to the production of a semi-auto variant of the MG34 is also included. Good overall.
