OK, then here is the unidentified bobbin:
It is flat on both sides, one piece machined with a slot on each side at the axle. There is also a crosswise grove for the bobbin winder to latch into in the axle. The bobbin is 7/8" in diameter and 1/4" thick.
Can anybody tell me what this fits?
I know it does not fit our Featherweight or 9W-7 though they are similar in shape.
