Great stuff and thanks!

Some c. 1870s Parker Hammer Lifter guns are labeled "Twist", but are clearly laminated steel. The Parker "Fine Laminated" offered on Quality I and H hammer guns in the 1899 catalog, which is a grade below the "Fine Damascus" used on Quality G guns, is likely One or Two Rod "Laminated Damascus." The 1888 Colt Patent Firearms catalog also has a quality gradation from Twist to "Laminated" to Damascus and Hunter Arms used “Laminated Steel” on Quality No. 1 L.C. Smith guns 1892-1898.

1893 10g Quality O Parker with Laminated Steel brls


The Parker, Colt, and Smith 'Laminated' brls are unlikely, however, to be "Best English Laminated Steel" since they are on lower grade guns.
