Nice 3 Iron "Oxford" barrels
I believe both barrels are lightly stamped with the SB&Co T of Sanderson Bros. & Co; T possibly Tacony Iron Works (1881-1910) of Philadelphia. Or maybe 'F'. We haven't found an 'F' steel works.
This is a fluid steel Lefever H with SB&Co G; G possibly D.G. Gautier & Co. listed as an agent for both Sanderson Brothers & Co.
We think SB&Co acted as an import agent for the Belgian rough forged tubes
