The color scheme you're describing sounds like the Touch M100, Touch M400's.......or maybe the D100, D300, D310, D810......I think they were pretty much all the same radio, just different housings and channel capacities.
Although most of their radios could be used for either a base or mobile, Regency had a radio for the home, and a different radio for the car. The K100 was a much wider radio with a wood grain case and was probably the same radio as the M100 and D100 in a fancy housing.
I bought my M400 around 1981, and they hadn't been out long.
