RCA CTC-115 question
 

I am new to the world of vintage TV, but have collected and restored numerous pieces of vintage ham radio and stereo gear over the years. I have recently come across a RCA CTC-115, which, except for a few minor wear spots due to its age, is in excellent functional condition and am wondering if this item has any actual collector's value? I really haven't been able to find much info on it.
Thanks...Fred
