I own one. Here's a little snippet I found somewhere on the web: "In 1948 Charles Houvenaghel, an employee of Leblanc, patented his 'double-Boehm' clarinet, which simplified fingering for the left hand, and made Eb1/Bb2 part of the normal scale. The rest of his clarinet resembles a normal Boehm-system instrument."

And this from "The Modern Clarinetist": "A fingering system patented in 1948 by Charles Houvenaghel (1878-1966), of Leblanc. In this system the lower joint is that of a normal Boehm system clarinet. On the upper join there is a plateay key for L1 which, when depressed along with L0, produces Eb4 (rather than E4, as on the normal Boehm system.) This means that the pattern of intervals produced by each hand is the same: a whole step followed by a half step. On the double-Boehm, E4 is produced by L0 and L2. The plateau key is also pierced with a small hole, to facilitate the pitches of the altissimo register. The instrument had refinements of tone hole size and shape and omitted the bridge key between the upper and lower joints."

Mine came with a DB mouthpiece which unfortunately had split and been glued.
