Like a lot of pipe brands, it is hard to trace the exact lineage on it, and I am far from a pipe expert.
So far as I can tell....
Briarcraft made a lot of pipes. At one time they were a big pipe line. Also made some pipes for other folks, or stamped names on them. L.L. Bean being one. They also made secondary lines, Smokemaster being one of them, and that line was bought by Grabow in the mid 60's. As well, Wimbledon was a secondary line.
So, the pipe was advertised on Ebay as a Comoy's Wimbledon pipe, but it is more along the line of a Kaywoodie in style and value. There is a Comoy's Wimbledon pipe, but this is not it at all. I do think it was made prior to the 1950's, but that is only a half educated guess. Or a minimally educated guess.
Anyhow, it is a handsome pipe and will likely smoke well, if what I am reading about the Briarcraft pipes is true.
