Found new owner
It was really a pleasure to renew this pipe because both briar and vulcanite are still of very good quality. And we are certain that smoking of this featherweight (it weights 23 gr only!) pipe will be a pleasure as well!
The pipe markings are "LONDONER \ LONDON.ENGLAND" and "326S". The lenghts is 13.5 cm, bowl's hight is 3.7 cm. External and internal diameters of the bowl are 3.1 cm and 2.1 cm. The depth is 3.0 cm and this pipe weights 23 gr. Briar, vulcanite stem, no filter.
