Sorry, the gun is on the way back to TX. It had two fine pins that stuck out of the action and a strange half round that was below the floor of the action. The strangest thing was the 2.75 rechamber and reproof for 1 oz loads, I believe they were Whitworth tubes.A 20 bore was not common then , as I recall the sn was in the mid 6000 range. Care to make a wild guess on value?
