Please dont be confused ,several old writers used the term "English Walnut" to imply the walnut wood used on English guns .Not necessarily English grow wood. Although I have seen some very pretty English grown walnut with pinks and blacks in the grain , our climate tends to give native grown wood a lot of shakes that tend to show up when the wood is seasoned.Great for furniture . I do know of several people that have tried to use home grown wood ,but with limited success . The last thing any stocker wants is to supply wood that is likely to come back on him so most wont use it unless the customer supplies it and accepts the risks.
