I have it as a very dark blue. Can't decide what it actually is. In later photos it looks blue and has blue/white checkering on the cowl
Lyric1? Paging Lyric1.
After looking at the images online & in a book I have.
The spinner and the band behind it on the engine cowling are black.
A few images of the same aircraft.
First one not much help.

Second one is a complete photo I found online not sure you have that based off the first image.

Third one is at a later point in time.

Now based off of the third photo I found other aircraft from the same squadron and these colour photos show some interesting facts on the checkers.



The squadron is 15th TRS.
The last image explains the later schemes.

So blue spinners became the norm when they painted the checkers on.
