Oh, yes. Please do. Mine's on the bench right now.

Sure thing. Funny - there are three of us (Eric, Lee and me) working on this uncommon model right now

Interesting coincidences like that seem to happen a lot in this hobby....IIRC there are only 2 known examples of that 50's rectangular color westinghouse set but both materialized within a month of each other and were posted about here.

I scanned the RCA 721TCS service data and it is available to download courtesy of the Early Television Foundation. Owners manual coming soon.

Thanks for scanning and uploading that, Bob. I managed to restore mine using the 721TS data, but it made for a bit of headscratching when rewiring the remote speaker harness that only the TCS has...

I finally had the time and patience to remove all the wood screws holding the front on. I sure didn't expect the whole from to come off like that!



The speaker is in very good condition and I found the pilot lamp and holder to be intact down at the bottom.


Unfortunately, the donor plastic dial scale is cracked.


I removed the speaker form the donor chassis and it slid right into the cabinet


Then I installed a genuine RCA Victor 10BP4.



Finally, here it is all back together with knobs. If I had access to an outlet, I'd have fired it up. That will have to wait until and I move and get a workshop setup again.
