USN - 45 deg vs 60 deg Code Letters?

[Pat C]

Was trying without success to decide if there is any logic to when the USN/ USMC used code letters with the 45 degree cut offs vs the 60 degree cut offs on post-war aircraft and would be grateful for any insight from BM'ers. I had assumed the USN always used the 60 deg letters but have found lots of pics where it looks like 45 deg letters as used by the USAF are in evidence, and sometimes a mix of both on the same aircraft. And forgive the real idiot boy question - are code letters on USN aircraft are black rather than Insignia Blue?

@Dana Bell is probably the best man to ask this. He knows the markings and the colors of the USN/USMC aircraft.

Thanks Andy - I think 60 is 30 just viewed from the other side of the protractor!!

Even though officially it was 30deg there were still plenty of angle variations (and ratios) since the numbers/letters could've been applied at squadron level using simple masking tape (by eye) or locally made stencils.
