Just curious-- Craig, as you are the "el primo Foxist" here- Have you ever seen and examined one of the Philly 20 3" Burt Becker bored Magnums. The late T. Nash Buckingham's friend Hal Bowen Howard had one, it was mentioned in one of Nash's stories about a waterfowling hunt he and Hal shared.
I have a Sterlingworth 20 made about 1935 in Utica with 2 & 3/4" chambers, 28" barrels, DT, EJ-- great bird gun. But a friend also has a similar 20 Sterlingworth- 30" barrels, DT, EJ- and his chambers "mike" at 3" even with a Galazan chamber gauge- as well as the old rolled up index card stunt- But it is not a HE 20 by any means--
