Oh shoot yeah that's cool! I've been trying to "make" a box of repair parts for myself, after finding out what the local hardware store is charging for those parts!!!
Anytime I find a Crescent wrench I grab it- even if the handle is bent, it's broke or rusty. I disassemble it for the parts and sort it out into my stash box. Next time I find a NOS missing a part, I can fix it.
