Hello, I have long been bitten with the bug of "analog" photography and finally decided to make the first step and buy the required darkroom equipment. I have found a used but in otherwise excellent condition Kaiser VP350 35mm enlarger, which according to the manufacturer's manual is upgradable to 6x6 by changing the condenser (article no. 4477) and film carrier. I have searched the web for this particular condenser and could not find much. Is the condenser for this model compatible with other condensers, does anybody know of a source where it can be bought? Thank you.
