Trio of refinished barrels

[Bruce Day]

I was thinking those were barrels of Parker made Twist . If not, is the consensus that they are English Fine Twist ?

[Drew Hause]

John Davis' research suggests that Parker Bros. made Twist and Laminated Steel barrels in-house 1877 to possibly 1882.

Lifter era catalogs listed "English Twist", but there are Lifter examples with ribs marked "Stub Twist" and "Plain Twist".
Possibly someone could check an early top lever catalog for the descriptive term?
1890s No. 1s were listed as "Fine English Twist"; Quality T hammer guns with "Twist".
