I agree that it’s a pre 1970 Super Course with a replacement fork. The earliest Super Courses didn’t even have chromed fork crowns, although I think that by 1970 they did, but this one is not correct. It looks like the original brake bridge was removed and this one probably brazed on prior to the repaint. Here are a couple pics of my 68 showing the stay treatments, lugs, cable stops, and fork crown.
