Does anyone have any idea what the scarcity of the Chinese copy of the 57mm UBR-271 APHE-T is? It is 57mmx480R and was used in the copy of the ZiS-2 (Type 55) AT gun. I have one that is complete to include the copy of the MD-5 fuze and lacquered brass casing. No time right now but I'll post pix later. Cheers, Bruce.
