I note on page 2 that he states in 1904 one "Désiré Mineur" of Prayon claimed exclusive rights to "Chain Pattern" Damascus. My F grade Lefever with Chain bbls (SN 38025, 1901 "IF" in sequence) is marked S B & CO.
I also note in the lists by the bl makers they list an "UnTwisted Damascus" described as those in which the bars are wrapped around the mandrel without being first twisted. The British & US Gunmakers seem to have universally adopted the terminology laid down by First W Greener & later by W W Greener in that "Damascus was applied only to those bbls which were first Twisted in the bar prior to winding, while those which were not were referred to only as Twist. These would also seem to be what Belgian Gunmakers generally stamped "Laminated Steel" (not to be confused with British Laminated steel). No wonder so much confusion of terminology exists. My personal preference is to follow the Gunmakers as this is the terms that will be found listed in their catalogs &/or stamped upon the finished bbls. Thus a spiral paterned bbl is a "Twist" & a figured bbl is "Damascus" of various patterns. Twist is then further broken down into Plain or "Wire" twist in which the wraps sppear as a continous strand & "Stub" twist in which the wraps themselves are broken into many short pieces joined together end to end. This term according to W Greener originated from the practise of forming bbls from a mixture of "Pulled" horse-shoe nail stubs & chopped coach springs. There was also "Stub Damascus" which used essentially the same mix, but was twisted in the bar prior to wrapping.
