A shining lightweight and surprising indeed Barling's pipe! It comes from a large family era Barling's collection produced for the Middlesbro Winter Garden, we have already represented a very similar Barling's Make Guinea Grain from this batch. But this pipe has only a script "Barling" logo stamped twice (see pictures). There's also no shape code (or it has faded over many years), but the letter "L" from the size mark is still visible on the other side of the shank. The Barling crossed logo on the stem is in place. Consequently it can be either another Guinea Grain pipe (and the grain is really impressive!) with the not accurately stamped and already quite worn nomenclature, or it's an early transition product stamped in such an odd way due to the company reorganization mess.
The pipe markings are "Barling (doubled)", "L". The length is 13.2 cm (5.2"), bowl's height is 3.3 cm (1.3"). External diameter of the bowl is 3.4 cm (1.34"), internal diameter is 1.7 cm (0.67"). The depth is 3.1 cm (1.22") and this pipe weights 24 gr. Briar, vulcanite stem, no filter.
