Lengthening LOP with Leather Pad

[Brett Rohrscheib]

With some very useful advice from Dean Romig, I was able to obtain my first Parker. It's a VH 16, 1 frame, straight stock with beavertail forend.
Shot sporting clays yesterday. As expected, the LOP is an inch or so shorter than I like. As the butt stock has some nice checkering, I'd rather not ruin it with an attached pad. So thinking of the lace up leather type.
Any recommendations for a custom lace up pad? Or any other ideas to extend the LOP without altering the stock?
