FWIW
David had his gunsmith shop at his home, nice equipped shop, he would employ a couple of gunsmiths and do work himself. He also had a very nice dedicated stock duplicator room.
I got to know him he would run my re-blue items, meaning I would get it all ready and he would give it the dip, did a really good job and very fair on price... miss this.
He always had a set-up at the Phoenix Crossroads Gunshow. He was big into TC Contender/ Encore stuff.
I moved away in 2010, what has happened since then ,,, I know not.
