Well folks, thanks to the generosity of Lightedcontrols, I now possess a "Frog-Eyed Kenmore" vintage unknown. Model #553561, Serial#C 525583. Anyone have an idea what year this was produced? It works just fine! I have been using the '56 Uni for a few days now and the spin on the Kenmore is so slow looking in comparison it is silly! Thanks! -Steve
