I don't know about the TVRS plug wires. Probabaly late 40's to early 50's. I'm fairly sure that they were widely used in production by 1958 at the latest. The R plugs was an early 'customer proving ground' used in production just for a few years just prior to e-ignition. I know of no e-igntion that does NOT use R plugs. e-ignition got started about 1973. As far as i know there was no e-ignition in any US production car prior to late 1960's at the earliest.
