Harry, we have seen other types of composite barrels on higher grade 8 gauge guns.
The grade of the gun is what generally determined which barrel steel to use on it. The various Twist barreld were used on grades 1 and below, regardless of the gauge.

A grade Finest Quality 6 Iron "Turkish"



A grade Premier Quality 6 Iron "Turkish"



Both guns were part of the Meachum order



re: pattern welded strength the winner of the Birmingham Proof House Trial reported in 1891 was English Best Laminated Steel. This is not the same barrel as Parker's Laminated Steel.



This includes actual tensile strength testing

The sample size was limited (getting back to finding Zircon's 30 barrels )
Pattern Welded mean psi after discarding the highest and lowest numbers:
Twist - 53,333 psi
Crolle - 54,700 psi
