I have just picked up this CAO pipe and wonder what type of tenon did they use.i wont have it for about 2 weeks but dont want to break it as soon as I try to remove the stem to give it a good clean
CAO got Bekler in 1977, and he carved for CAO until the mid-2000s when he retired. Judging by the case, this is probably from anywhere between 1977 and the late 80s or early 90s.
