View attachment 41863
Unusual conical spur on the briar more usual on clay churchwardens and on such as this larger than standard size although admittedly with a far smaller bowl than the oversized Cadger.
Made by C.Crop of London (1840-1924).
A.D.P.
Adolph and brother David Posener traded in London from 1861 until 1877 but he kept the A.D.P nomenclature on his pipes after his brother left the partnership - David being his middle name - until 1899 although the silverware was stamped A.P .
A.D.P. Trivia
(An A.D.P pipe features in Conan Doyle's Sherlock Holmes short story "Silver Blaze" (1892):-
"We all filed into the front room, and sat round the central table, while the Inspector unlocked a square tin box and laid a small heap of things before us.
There was a box of vestas, two inches of tallow candle, an A.D.P. briar-root pipe, a pouch of sealskin with half an ounce of long-cut cavendish, a silver watch with a gold chain, five sovereigns in gold, an aluminium pencil-case, a few papers, and an ivory-handled knife with a very delicate inflexible blade marked Weiss & Co., London.
'This is a very singular knife,' said Holmes, lifting it up and examining it minutely. 'I presume, as I see blood-stains upon it, that it is the one which was found in the dead man's grasp. Watson, this knife is surely in your line.'").
