That pattern is virtually identical to every H grade Lefever I have except one (it's steel). Lefever in their catalogs lists it as "Best London Twist". In Bob Elliot's book he quotes 4 articles from "The Sporting Goods Gazette" of Feb, Mar & Sept 1898 and June 1899 announcing the introduction of the new "H" grade Lefever. In these articles the gun was referred to as having "Twist" bbls. In William Greener's book "The Gun 1834" he described bbls being laminated & wrapped into a tube as "Plain Twist" & those being laminated & then twisted in the bar prior to wraping as "Damascus Twist". Whether this is technically correct or not is of little importance at this point in time. This is the way the gunmakers themselves referred to their bbls & to do otherwise now simply causes confusion & no on knows what type of bbl is being referred to. You can look at guns from the US, England or the "Continent" & those having been twisted prior to wrapping are referred to as damascus, those not being twisted but simply wrapped are referred to as twist. Note the Parker PH was listed by Parker as having twist bbls (it was not twisted in the bar but simply wrapped around a mandrel). This "Plain Twist" is also what is often referred to as "Wire Twist" though it was not actually wound from wires but as only the thin edges of the laminates are visable it gives that appearence. None of these bbls not being twisted in the bar were referred to by the gunmaker's (at least not quality makers, I haven't examined every clunker ever made) as Damascus.
