Wow! That's a treasure. Amazing how accurate it is! Definitely worth keeping with the paperwork, it could be a multi generational heirloom? Who knows, maybe 300 years from now, your great-great-great-great-great-great-great-great-great grandkids will be in the backyard (on moon base? Lol) shooting their star-wars-like phazers, and one of them will pull this out of a dusty, old force-field locker? They'll be like, "Whoooah! Cool! Let's shoot THAT, instead?"
