METAL OUTER BOWL
Photos and information from Doug Bisbee www.dkmetalpipes.com.
Doug has only seen two, this one and a copper anodised version. The stem is vulcanite and the inner bowl is ceramic.
As always if anyone has more, especially a manufacturer, let us know. Doug Bisbee figures it shares so many similarities with Aristocob it may well be from them.
the overall length of the pipe is 7 and 3/4 inches, the aluminum bowl area of the pipe from top to bottom is 1 5/8 inches, the bowl at widest point is 1 and 3/4 inches, the ceramic insert the inner chamber is 1 inch wide and approximately 1and 1/4 inch deep
