As I'd noted in earlier posts, the color circular test pattern design (first unveiled in 1965) originally had two variations, coded by region as per the order of a diagonal black/white wedge at the bottom of the outer lower right quadrant. TP's with this layout:



were for stations east of the Mississippi with 'W' calls; five stations were confirmed to use it - KYW Channel 3 and WIBF (later WTAF and now WTXF) Channel 29 in Philadelphia, PA; WCMC (now WMGM) Channel 40 in Wildwood, NJ; WFLD Channel 32 in Chicago, IL; and WNDT (now WNET) Channel 13 in Newark, NJ / New York City (the last actually confirmed to be color). And as laid out here:



was for west of the Mississippi with 'K' calls. Only one station, to date, has been confirmed to use it, and then with a B&W print: KAET (Channel 8) in Phoenix, AZ.

My question is, how many "old-timers" on this forum remember either layout, and who else would've used either prior to the wedges at bottom right being eliminated? Certainly those stations weren't the only ones . . . ?
