Rolf Litorin of Sweden came onto my radar in the late 1990's and immediately impressed me.  I believe he learned his bagpipe making skills from his father or grandfather.  He made a range of GHB and some were exquisite.  I don't know if Rolf is still making as I've lost touch with him. Good Friend Doug Wickham visited Rolf while in Sweden one year. Quite the experience.
