My 616 folder (with attractive leather case!) will be taking part in the fun. I am using two nickels as spacers with 120 roll film and the original 616 take up spool, and get 4 exposures per roll (expose when 3,6,9,12 show up in the little red window).
makes me want to give my 116 camera a try. I have 4 old Verichrome rolls for the 116. The camera isn't in near as nice condition as yours, but I should give it a try.
