Ca. 1950's Mauser HSc instruction manual which measures 5-3/8" x 4" with 30 numbered pages CONTENT: The only reference I can find to date this is a 1950's German language version from the 1950's which has an identical cover(the later Interarms manuals are different).It has complete instruction with photos and a 4 page, fold-out exploded view at the back.It states it is for the "New Mauser Automatic Pistol" and that it is "the fourth improved model". Excellent condition with light soiling on the covers
