I have just purchase a Ansco 8x10 studio camera. It also has a 5x7 back. I would like to know if anyone out there can help me identify the wood (looks mahogany) and anything about the history of this model. The standard lens is a Carl Meyer Anastigmatic f 4.5 303 mm (12 "). It goes down to f 45. It has T B and 1/2 tgru 1/50 shutter speeds. Around the ba se of the lens are the words Betax and Wollensak U S A. The secomnd lens is a Wollensack f 4.0. It is marked 18' Diffused Focus. It has f stops down to f 22. The third lens is a Bausch and Lomb-Zeiss Tessar Series 1c Its range of f stops is from 4.5 to 32. I don't find a focal length but I would guess that it is 35 t o 50 mm. This is for the 5x7 back. There is a shutter in the body of the camer as well as on the 300 mm and 35 mm? lenses. The diffuser lens does not have a shutter. I'm confused. Help would be appreciated. It stands on w ood and wrought iron tripod that has w heels. I got it from the original owner who hasn't used it in ten years. Thanks Jerry There are 6 8x10 filmholders and 6 5x7 holders. There are also 4 or 5 4x5 holder s. I would rate the package at 8.0 to 8.5.
