Helmet interiors?

[Bonf16]

I was just wondering how many helmets we have interior images for? So far I've seen ESB SE, PP3 and ROTJ but none for PP1, PP2 or Sandy.

I'm mainly asking because I wanna know how many helmets have the same vintage parts. Like do all 6 helmets have the same chin strap or how many helmets have the MQ1 boards and micro switches?

All helmets have/had the MQ1 boards and micro switches as far as anyone knows. They would have all had chin straps as well at some point however it all changed over time. For example, ROTJ lost the actual chin strap at some point but kept the parts with the D rings.

But then later appears to have lost everything and gained a harness:

There are pictures of PP2 from when Don Post had it (or shortly after). No chin strap or MQ1 at that time, but Don was casting it and seemed to have ripped everything out of it (as well as damaging the back of the helmet after getting it stuck in a mold twice). You can see left over glue from holding in the MQ1 and other stuff.

The PP1 helmet is lost to time so we probably won't ever see inside. Since it was the first to be painted we can assume it's fully decked out like the ST was. Currently this is the best we have:

The Mario/Touring helmet (Sandy) is in really rough shape in the Archives so seeing inside it probably isn't going to happen. All we really have is what you can kinda see in without the visor.
