8cm f2.8 Tessar. This camera, the only known example, is pictured in McKeown’s (12th edition, page 1051) and in ‘Zeiss and Photography’ by Larry Gubas (page 466). Gubas captions it as the ‘VK77’ prototype but there is an additional ‘o’ or part of a ‘6’ after ‘VK77’ – see pictures. The camera was bought by Peter Loy at Christie’s, South Kensington, March 18th 1999 (lot number 121, not catalogued as a prototype) and sold to a European collector. We recently bought it back from the same collector
