Yep, even straight from the production line back-when eyelets were fouled w/ paint and/or excess chrome.
It was SOP to use a tap prior to installing racks, mudguards and such to chase the threads. If no accessories were installed the OEM finish is still there to be cleaned up decades on with whatever else has accumulated since.
Except for Chicago Schwinns M5 was the most common size we saw on eyelets.
