Take a look in enfield resource, I emailed a lot of the people who mention enfield wood and they usually have stuff in stock thats not advertised. Otherwise springfield sporters often have brit walnut wood, and numrich gun parts corp the same, cheap too. I'd watch ebay too, and in addition go to ebay UKand Ebay Canada
, ifs its a sale for within country an email request usually gets folks willing to sell outside the country.
