cool new find, fire grenade sales kit by Red Comet

i recently aquired a red comet sales kit with booklets,sterno,melt keys,grenade holders, sales reciept book ,contracts etc. and most important one red grenade in a plastic container with no content and red color is crackling on the outside and one clear (full) grenade.The box it all comes in is in real nice shape and kinda opens up in a manner to help display eveything. could someone let me know a little about it and/or what it could be worth. my e mail is joekollars@live.com
