Grp. 6, with a chamber diameter large enough into which my thumb fits. The condition of this pipe is excellent, with crisp inner rim and a mark-free stem. The draw is wide-open and there is an Ashton “A” on the sterling silver band part of the spigot. I do not see a year marker in the usual place, but under the nomenclature is the number 210, which may signify something.
4.75” long, bowl 2” tall. Weight: 1 5/8 oz., 46 grams.
