Does anyone have a photo of the lock in the head of a system 7 machine?

I have 3 machines and not one of them is the setup the same or works properly....

Thanks,
Bob

OK , sorry for the Vague.

What is the relation ship of the Lock cylinder when it's locked? IE( is the key slot Capture.PNGup-down, Left right, Etc...)
What is it when it's unlocked?

Does the key turn through a full 90 degrees? Mine don't.

can the key be removed when it's unlocked? mine do not.

My Pharaoh will not even allow the locking mechanism to come fully forward because there is not enough clearance for the debossed ribs on the two stampings that move forward. they just hit the back of the BG.

Does the link that attaches to the cylinder on the cam lock go up or down. I have one of each.

Thanks,
Bob

Thanks Much!
