Odd that plain straight-grained dense walnut, which used to be the standard for across-the-counter guns, is fairly hard to buy. I had the same problem trying to match the new forend wood on a Martini to the original buttstock; people kept trying to sell me wood that was very plain open-pored and coarse grained, or very dense and "pretty". Finally cut the forend off a buggered up Rem 513 govt. issue .22 target rifle. Juuuust right!
