I had an interesting result of a buy from Gun List--which, at least, was much better organized than Shotgun News. (My wife called it Gun Lust.) Arranged to buy a 20ga sxs (no longer remember the make) from a guy down in TX. I'd previously purchased a 28ga AyA #4 from him and was satisfied with the deal. The gun arrived, condition as described in the ad--and in my conversation with the seller. Except it was a 16ga. Wasn't really looking for a 16 at the time. Called the seller, got his wife, who informed me he'd passed away a couple days previously. I expressed my regrets and kept the 16.
