The lost years?

[Steve D.]

Most of us are familiar with the various color sets produced from 1954 to 1957. There were several major and some smaller manufactuers. RCA Victor producing, advertising and selling the lions share. But as sales lagged and companies dropped their color lines who other then RCA remained in those "lost years" of '58-'59 & even 1960? I think GE had some color models. Does anyone own one of these model year sets or have any ads for these color sets other then RCA?
