This is a very nice clean Mg34 manufactured in 1938 by Maschinenbau und Geraetebau GmbH, Berlin also known as BSW.
The condition of this Mg34 is very good, dry firing is very smooth and this machine can be stripped down very easily. The fire control system has a semi and a full automatic section control so the operator can either fire full Automatic or select firing and on this machine gun this is very smooth in operation.
