I've revised one of the documents to cover the evolution of iron & steel components in pattern welded barrels
https://docs.google.com/document/d/1...m8-_AQPiA/edit
I have a crolle and a twist barrel segment for composition analysis
Strength & composition of vintage new fangled steel barrels is still here

Just got the report from a Parker DD 6 Iron "Turkish" segment Dave graciously provided. The tensile strength was quite similar to other crolle specimens at 55,500 psi.
Composition analysis now of 3 crolle and 1 twist specimens confirms the steel component in crolle barrels was low carbon low alloy AISI 1002 – 1005.
Much more detailed articles will follow in DGJ.
