I am actually not that surprised.
This is what happens when an auction house dumps a number of rare guns on the market at once. Especially guns that are so few and far between and rarely come onto the market.
To get better prices, they should have had two auctions 6mos. apart IMO.
The 350 Rigby went for a pretty good deal and the 416 Rigby went for $27K I think. Sounds like a decent price for both parties.
