The sources for various composite barrels for makers from many countries are pretty much the same. Drew can clarify.

I agree with Brad, and here's an example of 'British Best Laminated Steel', the winner of the Birmingham Proof House Trial

Steve: there were both English and Belgian 'Saxton' guns; the English usually have W. Bentley Pat. and Birmingham proofs. The Belgian were by both Ferdinand Drissen and Neumann Freres

Please keep in mind that both English and Belgian guns with Twist barrels are frequently marked "Laminated Steel", and the vast majority of tubes found on Birmingham, and some London, guns were sourced in Belgium.

So would the quality of the twist barrels be as what we have with our Parker Twist barrels?

Barrel quality should be assessed based on the overall quality of the gun.

I agree .This gun is as tight as they come. Barrels have very min. pitting I have not measured barrels walls but will soon didnt looked to be messed with , I just liked it when I saw it and what the heck 225.00 aint the end of the world .Some day I will learn to post pictures , watch out when I do.
Thanks
