Homelite XL-100 circular saw question

[Gottoolz]

I just got this saw and was wondering if the red guard is original.
All other XL-100 circular saws I've found online have blue guards.
Yeah, it's gonna take some work to get this one going. 90 psi is what the feller said compression was.

Mines blue and is the 8.5 inch blade model mine runs great but is missing the air cleaner cover.
Enjoy a great piece of American engineiring.
