Still working on my Sylvania

[Mick AV-8]

Looks like I have a mica (pictured) in this spot. Though it looks a little beat and that it may have gotten quite hot...
I do have quite a few of these plastic bummble bees..and though they are plastic cased..I am asuming they are still paper inside and will be trying to replace them.

Here is a mystery orange cap in the center section. I do not see it on the list...does anyone know what it is for???

Thanks
