I just had DH look for the external motor 201 I though was there and he couldn't find it. He says there is a 15 with external motor and a bunch of clones. Maybe I had it wrong anyway. I have some kind of long bobbin - good sized and runs off a motor. I'm not sure what it is. Looks like it would be good for FM with that harp.
I wonder why the Amish guy wanted the ones with potted motors so bad? I wonder how he was going to make it work? Go figure.
