Here is another old guy that collects (and uses) antique and classic cameras. Lately studying and cleaning up the Pre-WWII Ansco Memo. Some claim it was the first 35mm camera in the United States. Certainly the most successful. I suppose the QRS and Ellison bakelite cameras may have preceded the Memo...I haven't seen any documentation to that effect. And, of course, I have a few Kodak box cameras, some Zeiss Ikon and a smattering of others.
