I have an old Rapid Rectilinear from a junked folder. The shutter doesn't work, so I've thought of trying the lens on one of my Speed Graphics. Trouble is, the rear element is loose - shake it and the glass rattles, shifting about 1/8" in the mount. This lens is not worth sending to a shop for reglueing, so I'm thinking of doing it myself.
Any reason a common contact cement or Super Glue wouldn't work? I also assume that the rear-most position would be correct.
I'd like to see what effects this lens produces - maybe it will be hideously interesting.
