If it has a pin at the mount end push it in and see if something moves.
This picture shows what I mean - the is there on the 12 o' clock position.

Is there an A-M switch on the mount? If that is on A, then you won't see the iris until you push in the actuator pin, like Msiegel says. Put it on M, and you will be able to see, and change the aperture.
