The brand we are not familiar with. Our sources (books and web sites) don’t give any hints either. The most probably it’s an American pipe. Nice straight grain indeed!
The pipe marking is “NS”. The length is 14.9 cm (5.87″), bowl’s height is 4.7 cm (1.85″). External diameter of the bowl is 3.5 cm (1.38″), internal diameter is 2.0 cm (0.79″). The depth is 4.0 cm (1.57″) and this pipe weights 33 gr. Briar, vulcanite stem, no filter. We have patched a few not really noticeable dents and scratches around the bowl.
