I don't remember all the model numbers.
VCRs
BETAMAX - a "Sears" beta portable by Toshiba IIRC. Had to rig an RCA camera with a special plug to fit it.
VHS - the second model with an RCA name on it. Really a Panasonic. I worked in a TV shop and built that one from a few junkers.
VTRs - IVC color models 800 and 870 which was the insert editor. Still have those American made units and an alignment tape. I believe they are from the 1970's. The chroma was not down-converted but rather the whole bandwidth was put on tape and the outgoing burst phase was fidgeted to keep the tint correct. In the manual one can see the color machine just has one extra board for that job. The tape wrapped 360 degrees on those and the switching was done inside the vertical blanking
