A few years back, I bought a bunch of Beseler equipment that included a 23CII decked out with the Nord system for shooting multiple prints on single sheets of paper. It seems to have about every combo of lens sets (single, 2X, 4X, 6X and 8X), negative holders for 35mm and medium formats, etc. The lower lens stage has a modification added that allows sliding the various lens packs in and out. I packed it away, thinking that "someday", it would be fun to play with and might actually serve some purpose for me. I just had it out today and went looking on the net for information, documents, etc. I found nothing. Does anyone have any resources for information on these?
