I always think of you guys when I stumble across this stuff I'm sure you get the same kick out of looking at these relics. I'm waiting on a friend who lived in Guam to bring some photos of relics from that area she dived many wrecks while living there. She told me once two boys were tossings a grenade, back and forth. She said hey that's a live grenade they just responded "it's got the pin in it". I would guess that stuff gets a little touchy after 60 plus years.
