I heard about them very briefly after one of the big glass expos (I think it was AGE) and they seemed really cool. I remember they had recessed GonG tubes. American made, solid quality, that looks like a sweet stemless right there!
If you google "cal+med glass smoke" you can find one called the cmi-101. I was told this version was uber hard to find. If anyone has more info lemme know please. Ps: the tube hits sick as hell
