Gentlemen, I have a Model 311 double in .410 that has the old Tenite plastic stock(missing) and forearm. I am trying to help a buddy repair this gun and am trying to locate some wood for it,if wood is interchangeable with the Tenite.Can anyone tell me,first,if the Tenite and wood stocks are interchangeable,and second,if they know where I might locate a stock set reasonably? Thanks very much ,Marcus
