Here is the machine I picked up in the treadle top for $10.
I found the box of attachments, and it had two extra shuttles and 6 bobbins in is - and I looked and the above machine also had the shuttle and a bobbin still in it (probably a big reason I bought it in the first place).
I've got at least 8 white shuttles on hand, so I"m sure I can spare one - send me a PM if interested.
