Ok - we got some experts out there...how stable are the those bombs, land mines, detonators and dynamite from World War II ? Seriously couldn't those be unstable enough to cause considerable damage?
I could take a guess at one or two of them, but I won't call them out. That's their business.
I have a friend who has at least $500k in antique guns, and that is a very conservative estimate. It's a really unbelievable collection. He has piles of some of the most bad to the bone class III stuff as well. It must be nice.
