Among with the Canberra and Redonian the King's Ransom series belongs to upper middle grade pipes produced by John Redman fatory in London in the middle of the XX century. The idiom "King's Ransom" means also a very large sum of money (which should be enough to pay for the return of a kidnapped or captured king). Probably such naming means that a good pipe is also worth a royal person :-)
The pipe markings are "KING'S RANSOM \ LONDON MADE", "606 MADE IN ENGLAND". The length is 13.7 cm (5.39"), bowl's height is 4.4 cm (1.73"). External diameter of the bowl is 3.5 cm (1.38"), internal diameter is 1.8 cm (0.71"). The depth is 3.7 cm (1.46") and this pipe weights 37 gr. Briar, vulcanite stem, no filter.
