I have a brand new synthetic stock for your gun sill in it's box, I would sell you if you were interested in it.
The 1500 is the exact same gun as the Howa 1500, and the current Weatherby Vanguard (they are all made in Japan by Howa, and on the same equipment), so maybe you could find a wood stock from one of those if that's your preferrence.
If you are interested in the synthetic one I have, PM me and we can discuss it.
