Thanks for the comments, guys.
The paint is original. The camera flash combined with the reflectivity of the bare metal where the paint is missing makes the scratches look worse in these photos. IMO there are instances where aging gracefully applies. This cleaner wasnt designed with Glamour in mind anyway.
About the age, notice the rear wheels and the Patio setting on the DialaNap. By 1974 Eureka had already switched to the skinny rear wheels still used today. Also, by 74, the word "low" was in use.
