Keep looking for old stock of Konica 46mm school portrait rolls, all bulk loaded. The spools are hard to find, the paper, use used 120 paper cutdown. Find a roll of 127 and remark the 120 paper. Or build a 127 cutter for 120. Can be done.
Too much trouble, the Yashica 44 looks nice on the shelf. The Yashica 635 fills the small TLR need when I feel like shooting it (not often). Anything bigger and I am firmly into the 120/4x5/5x7/8x10 camp.
