Given the bidding, my guess is that the two bidders
had a pretty good idea who did it. With the premium, it was
a lot to bid for unknown sporter. Neither bidder was onsite
so they were just bidding on the photos and whatever else
might have been communicated via phone prior to the auction.

The action is too late to be a Wundhammer and the tang doesn't
look reshaped either. My guess is a Mielcarek, based on some
similarities that I see from this prior thread.
