I guess we'll all have to wait for the big brown truck. It looks like a Sedgley to me, too.

As to the auction house not mentioning the maker's mark, I was at an auction in San Francisco about20 years ago. Included were two custom Springfields with some unusual features indicating the same owner with specific ideas. The catalog just called them .30-06 sporting rifles; I found Barney Worthen's marks on one, nothing on the other. I called Michael Petrov and he bought both of them.
