pstlpkr, I'm learning...
Thanks, unclearthur! The Peterson I looked at was NOT a system pipe. My WDC Wellington has an almost identical system and the Peterson had a mortise and tenon set-up. I'm always a bit leery of pipes that won't pass a pipe cleaner since there is a tendency for some of my pipe to gurgle. Obviously, some of this could be due to improper packing, moisture content of the blend, ambient humidity, etc., but it gets annoying to have to fight with a pipe if it begins to gurgle and won't pass a pipe cleaner through.
