Hello All, I purchased a locam ii recently, and have been learning how the bad boy works for a little while now. With that said, one issue I'm having is with the aperture plate of the camera. I cannot, for the life of me, get the aperture plate out of the body. I've consulted the manual, which says to retract the pulldown claws and register pins, then to grasp the two knobs on the plate and pull straight outwards. I retract the register pins and the pulldown claws by using the film threading knob on the outside of the camera to get the pulldown claws out of the way, then I turn the register pin retract knob 90 degree clockwise, and pull the pressure plate back, and the aperture plate doesn't budge. Any ideas why? Am I doing the wrong things to get the register pins and pulldown claws out of the way? Thanks for anything, Luc
