I knew the senior Mr. Turnbull from visiting his shop countless time. I pestered him more than I bought stuff, but he was such a storehouse of knowledge I couldn't help myself. He was a great guy, always patient with me and had an outstanding shop and a nice range. He never explained the relationship between himself and his son, and I did get to meet the younger Mr. Turnbull several times when he came into his father's shop for something. I was so sad to hear of the closing of the shop and range that I couldn't go to the auction. A few years passed and the younger Mr. Turnbull's company had a table at a local gun show. I knew of his work before this, but I'd never seen an example. I was amazed at the quality of the work. I had a couple of things that needed more attention than I could provide, so after a year or two, I asked the representative from Turnbull's at the show if we could make arrangements to do this work. He said, "no, we don't do those any longer." Well, that was at least five years ago now and I'm still hoping that Turnbull's will change their policy and do the work on my guns. Their work is worth the wait and I wouldn't trust them to anyone else! Best of luck and make sure you post some before and after pictures after the work is completed.
