Anyone ever detail-stripped and successfully reassembled a 50 f2 collapsible Zeiss Sonnar in Contax rangefinder mount? I have one with a good bit of what looks like oil fog inside it. The iris works very smoothly; just want to get in there and steam-clean the glass.

I have a strong light, a work surface relatively free of crumbs, a fine selection of ball-peen hammers, and forty gallons of fresh-brewed hydrofluoric acid. Should I attempt this?

You're very kind, sir. Thank you. Mail sent.

Oh... will the sketch indicate where one applies the cold chisel?

just hold the chisel by the pointed end and rap sharply with the handle on the center of the front element

Mr Oleson, your sketches were spot-on. Worked like a charm. Just a warning to anyone else who tries it, though- beware the VERY thin shims between the barrel backseat and the inside of the mount. One of them was pure copper, maybe a thou' in thickness. VERY fragile. Breath would bend it. I have a hunch they're critical to the focal length, so be careful when handling them.

Aside from that, it was easy. I hardly needed the gas-axe. Thing just came apart after forty or fifty hard blows with a maul.
