Looks like one of Fred Picker's (Zone VI of Newfane Vermont) early cameras made in collaboration with or by Wista for him. He went on to manufacture his own handmade cameras and they were spectacular works of art in themselves. There are a few on Ebay right now. He also made wooden tripods for his cameras so if you want to keep the Zone VI vibe check out ebay too.
Unfortunately Mr. Picker died some time ago but he was a wonderful photographer. His
typed newsletters (printed and mailed, no web back then) were the gold standard in how to make and print fine black and white photographs. He explained how to use your gear to make photographs (rather than just owning gear). I still have them all in my library. He used to hold his Zone VI workshops up in Vermont and it was always my dream to attend one. His book on the Zone system is still the "standard of care" for learning the zone system in B and W photography and printing outside of Adams' three books (
Zone VI Workshop: Fred Picker: 9780817405748: Amazon.com: Books). Get a copy! He used to modify Pentax spot meters with improved internals and a zone scale on the exposure dial. I have one that I haven't used in decades but I'll never sell it. Priceless. He also made cold light enlarger heads with proprietary analogue exposure systems in collaboration with a professor from Harvard. All from a small town in Vermont!
He was a true American iconoclast.
