any one out there know their locks,wandering how old this one may beany ideas? it is 1 of only 2 locks that i have ever found,soaked it in olive oil for a short spell,i don't know what the body of it is made of,it cleaned up nice but the top bolt or whatever it is called is starting to fall apart,so i stuck it into a 2 by 3 clear plastic holder before it was to late!
