I was shopping on ebay last week and saw what I thought was a South bend steady rest that might fit my 9a. I didn't have a chance to get measurements from my lathe, and took a shot. I got it today and it's a good bit too big for my lathe. Now I'm trying to figure out what it fits so at least I know what I have. It looks to be about 6.5 inches to center which would mean a sb13 maybe. Any help figuring this out would be appreciated.
