Probably stored in the attic!! I've had a couple of kits that are 15 to 20 yrs old & the wood was fine. Like degrant said, the plans & inst didn't hold up. I have a Goldberg Super Chipmonk (K52 kit) I've had for quite a while, the wood & everything else is just fine. The instructions have holes all over them. I would love to know how old the kit is.
