My word I thought maple would be real cheap in the USA Bought several pieces of English walnut cut from the trunk around £55 for a bit say 60cm by 150 cm buy 5 cm thick , last slab was for the 8 g shotgun. I got all three rifle stocks on floor out of one big £60 blank incl postage , the wood ok. Find em on sawmill eBay uk The real stuff comes from Turkey growing walnut is big around those parts Big old trees with massive root balls. The English gunmakers go there , beautiful stuff , sells for £1000s. especial fir matching pieces, as shotguns come in pairs. Cheap guns and air guns usually come in beach . All very interesting
I wish you well
Ps around 1847 English walnut was used but by 1853 gunmakers we’re starting to use french walnut , don’t here much about french walnut now
