Nothing about this rifle looks right to me. Fortunately there are many members on this site with far more experience than me.

To me the rifle looks like a bit of a Frankenstein rifle. The RHS of the action looks like a sporterised P14, The LHS of the action has a Mauser type thumb relief. The bolt looks like a P14 straightened and re-welded. The stock is not of the quality one would expect from H&H. The while spacer recoil pad doesn't appear correct for the era. Has someone simply thrown together a whole lot of bits?
