RCA 8TS30 variations

[EdKozk2]

Hi,
I bought an old 8TS30 today at an antique shop today. The set has a 12 inch crt.
The front crt cover is made of metal with a clear plastic face. The front internal wooden cabinet brace was cut to fit the 12 inch crt.
I was curious if RCA sold upgrade kits for the 8TS30? The vert/horz hold and contast/picture control knobs barely fit under the crt cover.
I will try and post pictures tomorrow night.
