YC-75X100
The YC-75X100 is a large-format, instant-film TLR made in China, about which little is known. Hong Kong collector Wong Ting Man considers it one of the rarest items in his collection of 1042 instant-film cameras[1], and attributes it to "Shanghai Movie Ind. Institute"[2]. It is certainly a large camera[3] and "75X100" suggests this may be the image dimensions in millimeters. The nameplate could also possibly be read as VC 75X100.
