For the record:
Well, a customer of mine needed a cigar pipe but he
is used to smoke using my Aspida system.
Thus I had to "invent" a new version.
I started studying Zeppelin and Chris Morgan
cigar-pipes (as you can see in the last photo),
making many sketches and smoking a lot.
I made my own test pipe (dark-brown-blasted in the
middle), I tried it many times, made corrections and
more sketches and finally came up with my "robusto"
one that you see here.
