Yes it's a Boswell. Had my first smoke with it on my actual bday (world no smoking day) on Saturday at Zeitgeist in SF. Pretty large smoker friendly patio. Smokes very cool and dry, takes a bit of fudging to pass a cleaner, but takes to caking well. After one bowl it looks like it's had half a dozen.
A nice shotshell pipe! I've been ogling his fishing vest pipe and last week he had the same partial rustication like yours that sold quick. I'm thinking since I'd like a pipe that I can bird hunt with and not lose that I'd call and see if he could do one like yours but with a day glow orange stem, windscreen and a lanyard clip to attatch to the lanyard that holds my dogs whistle and e-collar transmitter. I'd then be able to just spit the pipe at the flush with no worries! Your GF is a keeper for sure!
