MK II Pineapple Yellow Grenade WWII
I have an original WWII MK II Yellow Pineapple Grenade, which is inert. I'm thinking of selling on Gunbroker.com-- are there states to which I can't sell, or other restrictions I may not be aware of? I don't want to inadvertently do something prohibited. Can you ship an inert grenade through the US mails?
