I was looking at one of the few pieces of demonstrator-made ironwork which I have collected. I really was interested in this piece, bought it at the auction - somewhat over my budget - but have no regrets.
This grille was covered to some extent in this post.
http://persimmonforge.blogspot.com/2011/12/buying-my-little-giant.html It was made by Mike (Smyth) Boone and Wendel Broussard at the IronFest Blacksmithing Regional Conference, Grapevine, Texas June 1-3, 2001. The conference also featured Frank Turley and Jeff Mohr.
It was terribly hot. I spent most of my time watching Mike as his work was closer to the type of work I was doing than Wendel’s chasing and repoussé. They both did masterful work and I really liked the finished piece and was lucky to get it at the evening auction. The next morning Mike also gave me the concept drawing done by Robin. I have enjoyed these things for over 12 years now.
