Identification of T-800 skull interior found parts

[retrogamer7200]

When looking through the T-800 reference photos put together by Conquerer_Worm, I found 3 that stood out to me. Those being pictures of the inside of a T-800 skull that was apparently built by Stan Winston School. As far as I'm aware, the inside of an endo skull was never shown like this in any Terminator media. I was wondering if anyone had any information/recognized any of the parts. Thank you

That piece circled in red looks like a "pneumatic bellows actuator switch" mounted on a Ghostbusters Proton Pack !!!

Well, so it does! I had a feeling that would be one of the easiest pieces to identify. Good eye
