there are three 5 inch versions 65mm and 90mm(early and newest) and a supercamera called multilens cam. 65mm film height is 11cm versus 6cm on the 65/70/220 if 70mm film was used. i dont know if there is anyone left who cam print directly 5 inch films using a roundshot enlarger. i think 50cm was the height-limit, right? brad lapaine has such an enlarger.
Interesting - the enlarger looks pretty neat. Probably never see one for sale though.
