I found these two pipes in a box of my Grandfather's effects. I haven't gone through this box in a while, it was fun. I found this Aristocrat Airograte by Yellow Bole and this Kirsten, which I find fascinating. I had a very difficult time taking the Kirsten apart, but finally got it apart and cleaned it completely. It was pretty nasty, but now it's clean and ready to smoke ;-)
I don't know much about either one, but they seem really cool and I plan on smoking them both!
