Cleaning out my storage I came across a densitometer and a slide duplicator. Both are for sale or trade. Please make offers. The slide duplicator is a DIA-NEG 2000. Clean with manual. I've never used it. It turns on but I don't have bulk rolls if film to test it out. The densitometer says Super Speedmaster Solid State Duo-Densitometer on it. Again it turns on but I've never used it. I do have the manual for it. Both items are heavy.
