That would be an interesting project. I have a CTC-5 Special chassis that I "rescued" from a field, but the CRT and associated neck components had been destroyed. The chassis is complete, though, and it will be worth evaluating with the thought of restoration. I only borrowed one resistor from it for my 5N chassis. I'd really like to have working examples of both types of chassis to go with my 4 and 7.
Good luck, and I look forward to know how you progress.
