Looks like the seller found the slide plate so that's good. Other than that, treadles don't come up often for what amounts to a half rack of beer. I hate stripping paint. I hate it bad enough to keep saying it. I don't know if you will find quarter sawn white oak or walnut under the paint but it will be worth the effort to get the paint off. Even with the paint at $15 I would have grabbed it and ran.
