Wow! I missed this thread!
Mine was a clay System one (it was then the cheapest System and I was a typical student without money to spare) bought in 1970. Has survived a lot of mountain climbing, sailing, a wedding, a little son...
It's now wery worn, having lost the glaze in the bottom part of the bowl and shank, has some superficial chips... but I love it!
I usually smoke it with aros, the clay bringing them an earthy flavour I appreciate very much, and it's still a faithful partner in all my sailing.
