A very convincing and very lightly smoked traditional English billiard made by Comoy's. Their McGahey series was made most probably for the McGahey tobacconist located in Exeter, Devon, UK. The shop is still open nowadays and you can easily find it on Google Maps. We haven't been there yet, but every English tobacconist is worth attention for sure! :-)
The pipe markings are "McGAHEY", "MADE \ IN \ LONDON \ ENGLAND", "34677". The length is 14.8 cm (5.83"), bowl's height is 5.2 cm (2.05"). External diameter of the bowl is 4.0 cm (1.57"), internal diameter is 2.1 cm (0.83"). The depth is 4.4 cm (1.73") and this pipe weights 50 gr. Briar, vulcanite stem, no filter.
