That's a great find in 2008! I don't think there will be many more forthcoming. The cabinet is a bit sad as you say, but at least it's a fairly simple cabinet. I think the value of a CTC-4 warrants putting some money into having a cabinetmaker rework it. With new mahogany paneling and a set of legs, it will be very presentable.
I got a GE 15" 15CL100 color set in similar shape a long time ago, and had a cabinet built for it, using only some of the original trim pieces and the structural frame. It is such a good job that (a nameless AK member) had a discussion with me in the 80s about whether it had really been rebuilt or if I was making it up
