The set is looking great! Keep an eye for RCA radios with a good bezel. It's possible. I have come across them here and there.
Thanks for sharing all the pics. I've been a radio/TV collector for many years and the TRK-5 is the "Holy Grail" to me. The TRK-9 has a more impressive cabinet, but it's rather large. The TRK-5 truly has the proportions of a radio console of the era which makes it so great to me. I give you credit for keeping it original. I would be dying to see the set come to life again!
Here's a video on YT of one playing:
