Skyraider tail code letters

[Black Knight]

I'm about to decal by 1/72 Skyraider in USAF Vietnam era markings.

I have to make up the tail code from sheets of letters.

Can anyone please advise me of the [real] size of letters of

1. the black AF 42

2. the white three number code following the AF 42

3. the larger TC positioned above number 1 & 2
