Here's an extreme closeup of one of the hangar shots I think I got from you, Dan. I see in the nose ID numbers what I took to be a dark outline around "76", but after looking again, it looks to me like it might be an area of fresher drab paint applied in the general shape of the "76" - maybe even behind the '6' only?
It is clearer here too that the letters of "ITSY BITSY" are practically touching,
but from the color photo above they appear to have a dark outline around them?

EDIT: A closeup of the color photo above, max-quality jpeg. It does appear that both "76" and ITSY BITSY are outlined - but is it black or a dark, fresh olive drab?

Or is this just an illusion caused by the camera film? E.g., the pilot in the center - doesn't his light-colored fur collar seem to have the same kind of dark outline I see on the letters and numbers? Look too at the shell casing eject ports, the nose gear struts, and the pitot tube under the nose - everything light-colored seems to have a dark outline around it....
