German training carbine in cal.22LR made by Gustloff-Werke , gun in excellent condition ,beautiful walnut butt, without any interference. It is practically a 98k in a small caliber, with bayonet and belt mount as in a combat rifle. A rare carbine. The last photo shows for comparison, both German cal.22LR Deutsches Sportmodell and KK Wehrsportgewehr training carbines.
