I just bought on Ebay for $72, a Schneider kreuznach componon 5.6 / 360 enlarger lens. I saw the photos and I thought it was small than it really is. I'd like to mount it on my 45MX with a stage conversion for a lens turret. The board it came with is larger than the standard Beseler 45mx lens board. My plan is to convert my 45MX to be able to print 5x7 negs.
