wilberness,
If you haven't already bought it, pass it by. It's a sorry design and it uses odd ball needles and bobbins. Substitutes can be had but it's the inside of the machine that's the bad part. It's got an aluminum skeleton with bronze bushings on the main shaft. These tend to seize up over time. There are also several nylon parts inside that will swell and bind up if you oil the machine. The rest is stamped metal parts. I think it was the Trojan Horse of cheaply made machines.
They are not a machine to buy if you really want to use one. I have naked pics of mine if you are interested.
