I have a 4x10 camera made by Richard Ritter that can be used to shoot vertical and horizontal images. The camera weighs 6.3 lbs. I also have 10 Canhan 4x10 holders that were used 3 times and are nearly spotless. The camera can also be used as an 8x10 , 4x5 or 5x7 camera with an optional, but not included adapter. I am asking $3000 plus insured shipping. I have 30+ references as a seller of photographic equipment. Pictures available upon request. The camera is located in So. NH
