Surprise! The machine we picked by the dumpster is a 15-88 in a #22 cabinet, born in 1933. Upon further investigation, it is in much better shape than we first thought. Decals are 90%, one leg has been stripped and will not screw on. The #22 is stamped on the inside of the cabinet. When we dared to fire it up, she sewed right away. Will post pics when her beauty bath is complete. Right now she is kinda naked.
