A butt graft and a grafted blank are two different things. A butt graft is a good way to make a short, or too low at the comb stock into a usable gun. Crossedchissels gave a good demonstration of how to accomplish that on this board. A true graft blank is the joining of Claro to English that is done in almost every orchard in the US. This is that type of blank. And of the many thousands of guns I have come across, if not tens of thousands, this is the first factory one I have come across. If the gun was priced at $300 instead of $500 I would pick it up just as an oddity. It is odd, rare perhaps but does not increase the gun value that much to me. Just a fun thing not a big thing.
