Cruisin' on my Bluebird
Hmmm.. Let me see.. Olive color paint in crank hangar (means it might have been completely painted that color).....
Could this sticker variation you are curious about with the olive background be for a Davis made National? They would have been available in olive drab. I don't know about the badge spacing on your bike.
I'm curious about the red primer on your bike with the surviving decal. Is that original primer or recently done (last 60yrs or so).
btw the Rollfasts were available with either olive drab base with black head tube or in reverse. I'm simply trying to show that Harley wasn't the only one to use olive drab around WWI.
