This is the first and only magnum-sized cavalier I have seen, and a remarkable pipe it is. From what I can gather it was a custom-made or "bespoke" pipe sold by a now defunct London pipe shop, manufactured by Comoy with sterling mounts at the bit and bottom of the shank and London hallmarks on the former and the initials "HC". The stummel was carved from a reverse cross-grained block of Algerian briar, completely unstained, and with a shank extension inserted, not to fix breakage, but purely for esthetic reasons and to balance the overall shape. It has a hand-turned "spit trap" at the bottom of the shank, and a lovely and perfectly intact horn bit on a notably stout (1/4") bone tenon, with orific lip.
The fit, finish and execution are of the highest order, even by today's standards, the aerodynamics first rate, and the condition outstanding in all regards, but for some minor waves on the sterling. The pipe was lightly smoked and cherished by its previous owner.
Highly recommended for the serious collector or smitten enthusiast.
