Calvin,

Here is a short writing I found on the internet that may help. Lam barrels are a form of welding steel while fluid steel is a solid ingot steel. The pressure references how they take imperfections, such as air bubbles out of the fluid steel to improve consistency (strength).

Laminated steel is more similar to twist or damasus - the main difference being that there is no iron strip, they start with steel formed into strips that are then joined forming them around a mandril.

My dyslexic mind transformed [It is a later top action hammer gun] into I thought they were talking about the top hammer gun with I believe laminated barrels hence the dumb question. Usually confused ch. Thanks for help getting things stright.
