Found new owner
The pipe markings are "Barling's \ GUINEA GRAIN REG", "WINTER GARDEN \ MIDDLESBRO' \ EL"". The stem has slightly rubbed the crossed Barling logo and the marking "Barling Design". The length is 13.8 cm (5.43"), bowl's height is 3.7 cm (1.46"). External diameter of the bowl is 3.6 cm (1.42"), internal diameter is 1.8 cm (0.71"). The depth is 3.1 cm (1.22") and this pipe weights 28 gr. Briar, vulcanite stem, no filter. The former owner had the habit to knock out ashes therefore the top of the bowl may look not ideally plain. There was a small chip patched on the shank, you may identify the track under a bright light. The chamber has been protected with a break-in coat.
