josephcross, I have to tell that nowadays I find it hard to discern some shapes. The description is from the maker and that works for me although I believe that the ukulele shape usually is more rounded on the bottom. I'm sure that others here can give more definitive information.
The pipe is 6" long and 2" at it's widest point. The chamber is 3/4" across and 1.25" deep. I don't know the weight yet. I'll get the pipe at our next club meeting later this month.
