A reliable, practical and affordable pipe made at John Redman factory in London approximately in 1950-60s. The name of a series comes from a name of the founder of the company most likely. Why to be over-modest? :-) A comfortable classical lightweight English billiard, nice grain, good smoker!
The pipe markings are "DR JOHN \ LONDON MADE", "34". The length is 13.5 cm (5.31"), bowl's height is 4.3 cm (1.69"). External diameter of the bowl is 3.4 cm (1.34"), internal diameter is 1.9 cm (0.75"). The depth is 3.6 cm (1.42") and this pipe weights 30 gr. Briar, vulcanite stem, no filter. The chamber has been protected with a break-in coat. The tennon looks a bit turned aside but the stem sits reliable and the air passage is visible and accessible by a pipe cleaner without any substantial complications.
