These auctions are a whole lot of fun. I, like the OP bought 3 guns in the same auction. All three were built by well known makers and after buyers premiums and tax were well below the cost of having the gun commissioned by the makers.
So far this year I have bought in auction rifles made by Jim Chambers, Herschel House, Jud Brennan, Mike Brooks, and Freddie Harrison and have gotten what I can comfortably call bargains.
Oops, I just let the cat out of the bag!
