I do know from experience that the OM finder (I don't know its "official" model number, but there was only one of 'em) will fit on M and later Pentax bodies, although it does fit rather snugly (compared to the Ref-M and Ref-A) (i.e., the OM doesn't go on or come off quite as easily as do the jen-you-wine Pentax finders). > For the old angle finder for Pentax K or earlier bodies, you need to file > it to fit, if you don't mind. I'm not clear on what it meant by that. Just what would you file? (The mount end of a K or older Refconverter would be decidedly sloppy when slipped onto the finder window of an M or newer body, wouldn't it? It seems to me that you'd want to shim it somehow, nor file it. (I apologize, Alan, if I am totally missing the gist of the statement.) Fred
