I think the first one was originally a TV cabinet, one of those big, ornate ones from the early 1950s. My aunt had a TV in a mahogany cabinet like that, with heavy wooden doors in front of the CRT and six heavy metal (cast iron?) door pulls, three on each door; when she moved in the late 1960s, knowing I collected old TVs at the time, she gave me the chassis (which still worked perfectly well and which I used for several years afterward) and put that nice cabinet out for the trash! The TV was a 1951 Majestic 16" b&w roundie with a 16GP4 CRT. The picture on that tube, with the chassis out of the cabinet, looked a lot like today's 16:9 HDTV pictures when viewed on a 4:3 analog set, but the cabinet had a mask that made the picture look almost round. The only difference was that the sides of the mask were bowed outward. The only other TV I ever saw with this kind of CRT masking was an RCA 16" b&w roundie console at our church in the 1970s; however, that set went out with the trash when the church was remodeled 15 years or so later.
