Sorry to hear that Dru has passed, we our getting old, it happens. Dru was the man that taught me how to make lost wax molds, he shot waxes for me in the beginning and got me into his foundry ...he sold wax machines, I think he made most of the sights on all the rifles we used. My wife and I also went out to dinner with him to eat frogs legs, he loved them, It was my first time at Friendship. Thanks for your help and knowledge my friend. Bernie pioneerarms
