Makers named their pattern welded and fluid steel barrels however they desired...always with an eye towards marketing. E. Heuse-Lemoine applied "American" names to several of the Liege patterns developed for the U.S. market.
When attempting to define patterns, it seems best to use the name that the original maker chose, recognizing that the same pattern might have several ie. English Two Stripe, Oxford,
Hufnagel, Damas fer clous, Damas Crolle', Remington's Oxford 2 S.J. and some 'London' patterns are all the same stuff.
Baker named the pattern 'London Damascus Twist', which Lefever called 'London Twist', and others just 'London'
