Downtube decal says it's made by Stella, and lists the same palmares of races as is seen on Stella downtubes.
With "safety" brake levers and cottered cranks, and the spoke protector on the rear wheel, it's clearly a creation of the mid-70's.
Not exactly a bike one would have seen in the "classic bikes" room at the Bike Expo in Seattle this weekend.
