Thanks, I’ll try this and report back.I would wipe these down with a clean white cotton cloth and some mineral spirits, then wipe on a tiny bit of silicone lube. These are pretty industrial beasts. Very worthy of a bit of time to clean up.
Very helpful, thanks. Not so much for this particular issue, but it’s a good reference. Elwood seemed to keep switching up the diffussion and heat absorbing glass stack. Mine has four sheets of glass plus the diffusion glass. At some point, a previous owner added little spaces of paper in the corners, which seems smart, to allow some air circulation. Yesterday I disassembled and washed the stack in dish soap. Once dry, I used some of the whiting polish that I use for preparing ambrotype plates to get them nice and clear.
You are correct. Those knobs are just above the negative carrier (and below the large filter drawer) and control the mask blades.Image stolen from internet warning:

The extra knobs around the negative stage control those masking pieces? I too was going to suggest Mineral spirits or maybe denatured alcohol. As for lubrication, does anyone know what the approved lube for Copal (and others) shutter aperture assemblies is? That may be
appropriate right?
