I will begin by stating this safe is unlocked, which makes things easier.

I will state that I have set and reset the combination on 3 wheel antique safes in which the wheels remain in the door.

This one throws me for a loop. Recently purchased at an auction with a R4, L3, R2, L1 4 digit combination.

The provided combination doesn't work, nor does the reverse, beginning with L4 for spinning.

Not a problem, I thought. I'll just reset it. Except it has a 3 wheel insert that comes out, so I am unable to visualize where the slots line up and determine the, or a, combination.

Any ideas?
