Svema OCh-45 16mm B&W Reversal Film, 4 x 30 m (expired 1976-84)

Svema OCh-45 16mm B&W Reversal Film - Lot of 4 Boxes, 30 m each

Four boxes of Soviet Svema OCh-45 - the classic black and white reversal 16mm cine film from the Shostka plant, rated GOST 45 (about ISO 50), 30 metres (approx. 100 ft) per box. All four are new old stock: three boxes are dated for processing before March 1976, one before August 1984. This is long-expired film sold for experiments: expect reduced speed and noticeable base fog, as with any 40-50-year-old stock. Reversal process - shoot it, develop it and project it, or scan it as a positive. We have two identical lots of four; the photos show one of them.
