I just checked out an RA-112, a "Mt Vernon", I believe. It's complete, but, the plastic cap on the tail of the CRT is snapped off, leaving a few wires and wire nubs exposed. I think the CRT still has vacuum, but, there's a Brightener attached, so it's probably marginal, at best. That's assuming I could resoldier the leads, etc.
One thing I just don't understand about many early TV's, and that is their exposed CRT Tails, just waiting to be bumped off. What's the big deal of extending the Cabinet Depth a couple of inches? It's not like you could push the TV Set closer against the wall, either with the Bump on a Rear Screen, or a Full Depth Cabinet.
Anyhoo, I like the RA-105/108's, with their Round Inductuner Dials, and nice Brass Bezels. The Chassis Construction, with the separate HV Chassis, I like as well. Looks more substantial than the later stuff. Whether it was more reliable or better performing, I don't know.
