This one appears to be a RC490 from 1966. In the catalog that I have it's the TOL 40" range. There is a similar one in the 1968 literature; model # is RC690. This one had the removable Teflon-coated panels in the main oven, rotisserie, meat thermometer, fluorescent lamp and infinite rotary-type controls for the surface units.
The 1964 catalog is the last one to list the available colors; which were Sunburst Yellow, Turquoise Green, Fashion-Finish Coppertone and Petal Pink. After 1964 references to color were vague and something like "each available in any one of Hotpoint's decorator approved color-tones or brushed chrome. Be sure to ask about colors available." Color availability varied by model (applicable to all types of appliances).
