the super corsa with eyelets was most likely for brevets, back in the days before cell phones, when you were truly
unsupported.
You had to carry stuff, or it might rain, and a wet butt for 150 miles is not fun. That's how it was explained to me.
I took the frame to a builder, since it already had no paint. He said "those are oem, and you'd better leave them alone."
i might add, the eyelets were on the tubing, not the dropouts.
