I agree with John Can. the stock looks like quarter sawn Beech and the forend is just through and through or plank sawn as we say over here. The only Pine I have seen that can take chequering is Parana Pine but it would not be suitable for a gun stock because it has a habit of twisting and not robust enough. Even we Brits used beech on some low cost mass produced Birmingham guns and it has stood the test of time, a good honest basic timber for which we did have a lot for a small island.

The only lessons in my life I truly did learn from where the ones I paid for!
