I got a Bergheil listed as excellent condition from an ebay seller... and alas it's actually in what I'd consider maybe okay to good condition and the interior is quite gunky with dust, grease, hairs, etc. I can work at the gross bits inside the camera housing with cloths and Q-tips and the likes, but I'm wondering about suggestions for cleaning up the hardened lubricant that some errant soul put into the front standard and focusing rails. Is there a way to remove the front standard so you can clean gunky lube out from the shift mechanism, or can you use some kind of solvent to penetrate in and flush it out (methanol? I've got some relatively pure methanol in the form of 'eclipse cleaner' for lens cleaning). Also: when I'm cleaning the interior are there any suggestions for avoiding marring the painted finish? Any cleaning solvents that would be best? I guess I can spot test on the paint in an out of the way place but I figured someone here has done this before. I'm also a little miffed at the seller for representing it as basically excellent condition, as I would have bid a bit lower had I known I had a cleanup job ahead of me - and it was without a lens so I bought it primarily as a nice clean body to put my lens from another scruffy body on.. but still it's a pretty sweet little bergheil and it'll probably clean up alright.
