I just finished refurbishing this estate pipe. It's stamped "Walnut Antique"on one side and" Algerian Briar" on the other. I don't know who made it, but the target logo on the stem looks like that of an old Linkman sub brand I looked at on the Pipe Logos web site. If it is as old as that, I'm surprised given the excellent condition it's in. The briar quality, fit and finish is top notch from my humble perspective. It has a push stem and maybe once had a removable stinger that is now lost. If anyone can tell me more about this pipe I'd be grateful.
