It’s a bit of a slow day here today – but we do have a new manual for you. It’s a 1956 edition of the Soviet armorer’s manual for the PPSh-41 and PPS-43. Everything you needed to know about repairing the burp guns, and the diagrams convey a lot even if you can’t read the Russian text.
You can download it here, or find it on the Original Manuals page of the Vault.
