Mike,
that's an optical illusion just the way the stock was layed down in the pic. The stock actually is a very conventional 1 1/2" DAC x 2 3/8" DAH with plenty of wood for a 15" plus LOP. Therefore, the pitch is also very conventional, where it is about 90 degrees to the comb it would be a few degrees when mounted on the action. No tang bending was needed. This was an orig straight stock Parker GH, #1 frame, 26" bbls (damascus), .040/.005 choke, 6lb 8oz little gem. I thought long and hard before comitting to restock it. But the stock was beat up bad and didn't fit me.
I'm no stockmaker and really struggle with inletting. I've done some rifle stocks over the years and a partial shotgun stock, a few shotgun stock patterns with Bondo, etc. I'm reluctant to do any further work without reading more and buying some more inletting tools to do it right on this one.
