I have just acquired a LPL 7450MK2 and a 150mm Rodenstock Rodagon lens. However, I have no manual for the enlarger and cant find a download for it. The problem I have is that the lens mount that I was given with the enlarger appears too small for the aperature on the enlarger. The external diameter being about 87/88mm on the enlarger and approx 84/85mm on the mounting ring. The mounting ring appears to be exactly the same as that on my LPL7700. That said, I have mounted the slightly smaller mounting ring and used the screw tightener/clamp which just pushes the mount slightly off center.
The next issue is that whilst the Rodenstock 150 lens does not appear to mount in the 39mm thread - the 80mm Rodenstock does no problem as do the Componons that I have.
I am sure there are simple answers to these questions but I can't find them at present - any ideas/advice more than welcome!
