I purchased new 4x5 and 5x7 Normas in 1969 and have put many thousands of sheets through them in heavy professional use. They look great and function as new. My favorite monorail cameras even today. You might find this interesting that my 4x5 basic Norma cost $365 in 1969. The Sinar rep told me there were seven people working in the factory at that time and they made 750 cameras total that year. They were totally hand made.
