Different Cowl Markings

[7D2N]

I was looking through some pictures for some reassembly and noticed these markings, no grease pencil letters or numbers like normal but I think the word (white) was written there at the time of red primer and has a stamped 3 digit number on the upper edge or the cowl. That number 675 is on the transfer case and the gas tank. Has anyone saw this type before.
