Another of Jim's historical footnotes is that he manufactured inner chainrings for the (Nuovo) Record Triple Cranks. I think that the smallest stock inner was 36 t from Campagnolo. Jim had made a selection in the low 30's. I have (somewhere) a NIB 31t and 32t. The package and graphics harken back to a simpler and more shop crafted (read; no marketing dept) look.
