Help with Keystone Safe

I'm looking for some help with this safe. Combination was lost over a decade ago. We think it's empty, but would like to use it. Does anyone know how many numbers there are and whether it Left-Right-Left or Right-Left-Right? Also, once the numbers are known, should the dial be returned to 0 before turning the handle? Does the key turn clockwise to lock and counter clockwise to unlock?

I've use the contact point method to locate one of the left turn numbers with 95% confidence and I think it's the 3rd wheel, but I'm struggling here. First ever attempt at this kind of thing.
