I have a 4x5 enlarger you can have, problem being is that's it missing the light source and the side crank arm is broken. I have the parts just not the cog, i did go to the trouble of drawing one up and it is on Shapeways if you want to purchase it. So good unit if looking to build a LED source.
It a Durst CE1000, have negative holders 35mm to 4x5 with 6x? ( its raining and cannot be bother going outside to look) and lens board
