Thanks for the quick reply, Bugyotsuji.
It does have a small hole towards the end away from the opening. It is about 5 inches long.
My grandfather was in the army Pacific arena during WWII. I assume that is where he got it. I don't know specifically where he was, he died in the early 1960's.
Now I'm in my 60's trying to wade through things, papers and such and trying to identify and organize. Not really my forte! Stories have been lost.
Thank you, Libby
