Frame was repainted a long time ago, possibly late 50s or 60s? Paint has patina and looks old. It should polish up nicely, if you want a shiny frame.
Paint was done in Modena Italy--see decal. Paint and chrome are in excellent condition. Judging by the opening inside the head tube, I guess that the down tube was replaced--see pics.
Rainbow stripes don't quite make it all the way around seat tube.
