This is Hobby Boss Corsair II.

Part N1 is transparent while M3 is not. What colours should they be?

Many thanks

My Hasegawa kit calls out H2 - Black

See page 2 of the instructions

EDIT: Little poking around and I believe it’s the AN/AAR-45 but couldn’t find any closeup pics.

The inside part is the lens, I believe, the clear one a cover that is jettisoned during flight. I believe the lens material is a substance called IRTRAN, which is a light yellow.

Not many pics out there of the AAR-45. It looks black in the available photos, but its probably due to shadowing from being under the wing.
