You have better eyes than me Craig.
We can't decipher patterns without first knowing how the 'lopin' was 'stacked', then machine rolled under high heat and pressure to form the rods

More interesting non-crolle patterns, possibly Damas Chine’

The only way to determine the ribband edge is where the 'scrolls' (sorry Steve smile ) are compressed as the edges are 'jumped'. In the middle of the upper tube there is a straight ribband edge weld down the middle of the squished scrolls (how's that for descriptive exactitude?).

Lloyd-the Birmingham Trial is here. Very few (obviously inferior wink ) "Foreign" tubes were included, by the British, surprise.

Crolle is old English. In Danish, krolle; Swedish, krulla; French, s'enrouler; German, rolle
“To form into coils or ringlets. Twist.”
“Crolle” was used in reference to damascus barrels in Liege and England by at least the 1880s.
The rods for all the patterns (but not Twist) were twisted, but Crolle patterns have a definable "scroll".
