So, I am cleaning out my mother in law garage, and I run into these...






Yeah, they're empty (DUH!).
Turns out my wife's Dad worked at the Rocky Mountain Arsenal and was given these two guys...
But what are they (please avoid the B-word, we don't want to be flagged now, do we?)?
Are they legal to own (you never know these days...)?
Do they have a value?
Who would buy them (are there GB equivalents for these kind of memorabilias)?
