old (1950's?) American Lock Co. (of Chicago) Brass Pad Lock
I lost the key to my antique lockbox... it has my nicest watch inside. The key had a symetrical shape, and I can feeel 4 teeth on each side when I go in with my pick. I wish I could see what the inside of this lock looks like - although my tequnique is more important. I have 3 picks that are a set of pick and hooks ground flat and a few other picks that fit and seem to push the teeth and hold. I really don't know what I'm doing. Any tips?
