Count the number of wheels as you turn the dial.
Where the drop is, you should be able to feel where the nose of the lever will so slightly catch in the gate of the drive cam, more than it will catch the opposite way.
That tells you the direction to open, and how many wheels, so you should have everything you need to determine dialing direction.
I would guess 4-wheel, cw- towards hinges.
