leonf, I have a Free Westinghouse ALB that's more or less the same machine, except it has the "turtle" motor. Not sure if you're aware, they were made to take a shorter CC1221 needle, but you should be able to adjust the needlebar to take 15x1 needles. Neat machines, I don't know if they were all aluminum, but mine is, only weighs about 16 pounds, pretty impressive for that era.
