I've got that one, pennycandy. Kenmore 1400, a pretty pale green. Low shank feet, too, since it was not a 1400-0. It has many sisters with the 'two dials on the right and white/red toggle above' look to the front of it.
Some White 77s are finally starting to pop up again on the local Craigslist. Very, very far away from here...
