I found out that my second machine (under $30) is a 128 born in 1940 in Elizabeth City NJ. My first machine is a 221K born in Clydebank Scotlant in 1952. I think I'll just get the power adapter and keep her as she started out in life. My question is for the 128; I see there are #'s after the 128 like 3, 11,12, etc; how can you find out which one goes with this one. Also, she did not come with a foot peddle so I'm not sure if she was meant to be hand crank or what. There is an electric motor and the power cord is USA. Do you have any clues? I have found manuals to download but haven't found the answers to these questions yet.
