this isn't really a reply to this thread, it is a plea for help! I was given a Vertical Feed treadle sewing machine yesterday and I had never heard of such a thing before. I have been reading all I can find on the internet, but I still have a few questions. I think it is in wonderful shape! it needs a belt to the treadle. The wheel is rusty. But all the parts move very easily and it looks pretty clean. It is in a beautiful cabinet with 4 drawers that lock. It has attachments loose in one drawer, and another box of attachments. The manual is in it, but is in bad shape- fragile with some tears. It only has one bobbin and shuttle and I have no idea what size they are to even look for more. I am very excited to get it cleaned up and use it! Any help would be appreciated. Thank you!
