anyone have image of F-4 block number "g"?

I'm talking about the little production block letters after the buno, here's an "ad" and "am" example - I'm trying to find a good image that shows what the "g" would look like. None of the pics I have with a "g" in it is clear enough to see it's specific form:

 

 

thanks

I'm looking for production block codes though, not tail codes.
