Battle,
The wood cost me about $180 which I know is ridiculous. Reason it was so cheap was that it was a quite thin blank, much thinner than most stockers would consider. Sold at auction as 'suitable for a small bore' I left a silly bid and got it!
One advantage of the Blanch back action SL's is that they are very narrow at the locks so a thin blank was fine.
The people involved in the stock's creation all agreed on one thing: the wood was horrible to work! Perhaps the vendor knew something I didn't!
