Neat guns and I'd imagine, don't know for sure, these are kind of rare. I bought one online several years ago. The gun had been in pristine condition until whoever packed it just tossed it in a box, disassembled, without and packing between the barrel and stock. You can imagine the condition of the stock by the time I received it. In this case it was not the carrier's fault. As I recall the gun was part of an estate being auctioned off by an attorney. They took the gun back but I would rather it had showed up in good condition, I would have kept it. I shoot a PA Hunter Carbine which has dimensions close to the Buckeye and really like it.
Sounds like you made a good score. I'd be curious to know how it shoots.
