After searching numerous images on the net and not finding answers, what is the official paint scheme for a Galil rifle?  Are there subtle differences between various models? From what I can see, it's always the outside of the receiver, gas tube, fire/safety selector, and dust cover that are obviously painted.  Beyond that, I can't tell if the following parts are painted or not:  magazine catch; the "guts" inside the rear sight housing; the rear handguard holder; and the charging handle.  I saw a close-up picture of what looks like paint flaking off of a charging handle while the rest of the bolt carrier looks parkerized.  Does that sound like a correct assessment of a factory rifle?

Reason I'm asking is that I'd like to finish my Golani with the same pattern as the original.  Thanks in advance for your help!
