Admiral was in stores in January, 1954, Westinghouse March, 1954 and RCA April, 1954. Availability of all sets were very limited. As an example, the CT-100 wasn’t available to purchase in NYC until mid May, 1954.
I don’t know what demod scheme Admiral used with their C1617A.

You nerd sniped me on that last line...After a visit to earlytelevision.org I now know it's an I/Q demodulation set.
The GE 15CL100 that IIRC also beat RCA to market is an R-Y/B-Y set with the added weirdness of not having a chroma osc but instead a crystal ringing circuit like a portacolor....The portacolors demodulator comes from a different brand of early color set the 1957-62 Motorola 21CT2.
I now want to read more about what demod circuits the various early color sets had.
A few weeks ago I got out bid on a 21" Raytheon that I happened to have the Sam's for and it's demod was a fairly novel design.
