Here's a little writeup on him from another website.

Tony took over the operation of Dave Wayland years ago when Dave passed away. Dave and my dad were great friends, 20 or so years ago he gave me a pair of roughed out blanks from a tusk he had in the shop. I was to hold on to them while they got comfortable with their new shape, and think of what design I wanted for my 1911.
While I ruminated, Dave passed on. I'd been tipped by someone that Tony got his tooling, materials, and contracts - and when I called him he arranged with me to take the ivory stock and set me up with a set of grip stocks.
I've had the grips he made for me for about three years now, and I'm perfectly happy with them.

Cheers
Tinker
