Can U Identify These Aperture Plates?

[Jim Cassedy]

These two aperture plates were in a box of assorted cinema odds-&-ends that I acquired
several years ago. I know I've seen this type of plate before, but my mind is a total blank
on which type of projector they fit. I'm sure somebody here knows the answer. THANX!

Simplex with a turret, prior to Millenium model but don't remember which exactly

[Tim Androes]

on second thought...went and looked thru the manuals for Simplex...those look very similar to the illustration for PR2000 Millenium apertures except your's have an extra small hole

[Randy Stankey]

I agree. They are for a Simplex with turret and aperture changer.

The projector has a slider that runs on a rack and pinion. The clip that holds the plate was always coming undone and the little, metal flap would fall open. I don't know how many of the projectors I used to service would always seem to have splicing tape holding the clip shut!

THANKS, Tim and Randy! Simplex is probably a safe assumption, and makes sense
since there were a few other Simplex parts in the box, like this 5-Star soundhead door.

Hey Jim. An old dog here who has been out of the business for 12 years and have not posted for ages, but they are certainly Simplex plates. I second Randy's reply. He is correct.

For sure! I filed out a lot of those over the years...
