M42 Bellows II in unused condition...

It's been fun going back to the 1960s and exploring Yashica's M42 gear and in one of the brochures Yashica referred to using long lenses with their bellows which seemed an unusual recommendation. 

Finally, a complete bellows with its instruction sheet has made its way across the pond and there for all to see are magnification scales for a 135mm Yashinon lens; who'd have thought...  They never considered the option in the photo as the only calculations close to the 60mm Tomioka were for the 50 and 55mm Yashinons.  I can't wait to try the Yashica/Tomioka combination...
