Thanks for offer. Basically I can't figure out how to install the golden color roller on the stand. I would appreciate a detailed pic of the back of the enlarger.
I'll get a photo tonight. That roller is a spring. It should attach near the top of the column. It helps keep the head from crashing down when it's not locked.
I have this enlarger, and it came with the C7700 manual in the box. I assembled it with that same manual as well, so they are basically very very similar. I had emailed a copy of the manual I scanned awhile back to Mike Butkus but I am not sure he posted it on his site. If you dont get you manual from paul, I can also email you my scans.
