Wow, maybe I can prove useful...lol..
The passenger side 60HP emblem on the '64 is in pretty nice shape. There is no evidence of paint on either the hood badge or the 1200 emblems. Seems odd to me that the 60HP would have held up and the others not. Perhaps, being above the beltline, they took more weather abuse.
I would definately call the 60HP badge 'Schoolbus Yellow'.
I really need a tripod for those close zoom shots, sorry the first one is so blurry. Too much coffee maybe...
Hope this helps.
