I am currently looking for an enlarger that can handle 4x5 and I ran across a gentleman who says he says a Omega "D" enlarger. I can't find much on the web about an Omega D enlarger, but of course lots of the D2 D-II etc.. I did find one thing that said there was an D model that was even older than the D2 series. Can anyone tell me about this enlarger? Is it basically a D2 or does it have some disadvantages comparatively?
