Hi All!
My 142 is white, with the grey toeboard. Must be only the white ones came that way. The A700 came in 1961, after the 142. The only change was the gold dot glass panels and the grey buttons and dial. The 142 had several revisions, from the two piece lid and electric lid switch to the single, modern style lid with a mechanical switch, and from the pivoting motor to the modern spring slide motor carriage. The last A700's had a rinse temp selector on the top of the console.
