gazzo50 is it possible it's a mistype and you've got a 222 or a 221? I've never seen a 322 and while I might have missed it I think I'm right that there isn't a FW with that number?
If you've got a 222 congrats they are even rarer then a 221...if you've got a 221 they are wonderful little workhorses. I've had mine for about 10 yrs and love it for piecing, tho I didn't care for the way it worked with my zig zag attachment and a lap sized fleece backing. I will try it with other, less thick material tho.
