IIRC I think the last of the 90 degree monochrome tube sets would be about 1965 vintage at the latest. Most of the low line makes such as Bradford, Airline, Muntz, Olympic, Sonora, etc likely still used the older tubes up 'til then. Cheaper, as the major companies had phased them out, and NOS could be had for less.
That's a pretty-looking RCA floor set.
