1969 Chevrolet Bluebird school bus
 

I have a 1969 Chevrolet school bus I am trying to find information on the rarity and possible value. I can not find an image or descriptions that matches the one I have. It's 26ft long and has a hump at the top, back about a foot from the windshield, made by Bluebird. The bus was converted into a motor home in the seventies. In its previous life, it was a school bus on a military base in Alaska.
