The removal of the shells from the frames went without incident and I think it was due to my new invention, the Marx tab bender. I sharpened the end of a small slot screwdriver to a fine point and then bent a very small portion of the end to resemble a tiny pry bar. It slipped under the bend tabs easily and I gently pulled them up and then straightened them with a needle nose vice-grips to get a straight tab. I was shocked to find that all the window strips were tabbed as well and the celluloid film was incredibly brittle but again, they removed fine if slowly... I gave the shells a scrubbing with Dawn and one of those semi-soft plastic scrub sponges..they were oily and pretty well gunked.
Steve and TrainsR Me..those are some fine looking examples and I thank you for the inspiration to press onward. Anyone who wants to see the innards of the shells and the tabs to be fought, let me know. I used a chemical used for automotive use that neutralises the rust process, prior to primer. A great deal of it was ongoing underneath the surface. It turns rust black. You can see hairline scratches that were beginning to eat the metal.
