This is a pic of one of the many ashtrays that I handed out during my command tour... the machine shop would turn these from a 5 inch shell casing and then affix a small plaque on it that said one of two inscriptions:
"A good smoke is always on target."
or
"A powerful circle, bound by the pause of a good cigar."
and:
"Presented by the Commanding Officer, USS JH, on the occasion of your visit."
Wish I had kept a few more of them when I retired....
unique and that machine shop did some amazing things for its size.
Carry on.
