These are just for parts, maybe useful to someone. The Premo C is what I found interesting. You don't see them for sale much either. It has a primitive lens system, meniscus? It looks like a 4x5 camera. I'm not sure how to work it, but it has the aperture ring built in to the lens board. The other is 5x7 Tele-Photo Tele Poco with a symetrical lens that needs cleaning and has some edge seperation. The shutter fires, but how accurate is not known. These are for parts only, the 5x7 could possibly be used and that is a maybe only. They are sold as is for parts either way. Email or pm me if interested please. Price is 50.00 dollars for the pair plus shipping to the US only please. Thanks, Mike.
