Time to resurrect this thread, not wanting to hijack Al Jones' post of a few months back. Beautiful pipe, Al!
New one here. Unsmoked 1992 Sovereign SG4 with a Sterling cap and band. Honestly, the silver work is a tad sloppy with some excess glue on the bowl. I wonder if it's possible that it was re-glued at some point in its lifetime. Still, IMHO, a very handsome pipe. Elegant without being fussy.
The stem looks like Cumberland. Were any of the Ashtonite stems brindled like Cumberland?
Also, there's no size designation, unless SG4 implies size and not the degree to which the grain is straight.
