Yale two-key lever lock from bank safe

Removed this little guy from the open safe on the left of this picture:



I've never messed with a lever lock before, so I wanted to take it apart.



I assume the teeth on the levers are an anti-picking measure. Looks like they'd be pretty effective.



4 levers for one key, 6 for the other.





Looks like someone ground the lug off the bolt so it only requires one key. I see the drive lug for the toothed levers is also notched, making our lives even tougher.

Does it say Yale anywhere on it? It looks like an S&G 4440 double little nose to me

Yes the outer case is stamped Yale.

Wow it should just about qualify as a crime to destroy an older Yale lock by grinding the fence off it.
Be interesting to know if the bank knew, or just thought their key was actually opening their side of the lock?
