Cruisin' on my Bluebird
It looks like you have the makings of a nice bike! I think they went to the chrome fenders in 1958, and a front rack with a ball light instead of truss rods and a Rocket Ray. But it still has the 1957 style head badge, so probably late '57 or early '58. Unfortunately I don't have a 1958 catalog.
