I would speculate that the original rear derailleur took a dive into the spokes, thus bending the dropout. The replacement may have been chosen for the color scheme or because it was a better mech (i am not fond of Hurets of that period). You can get the dropout fixed when you replace the seat tube.
What tubing do you experts think this is?
Nice bike and I sympathize with your disappointment on finding the broken tube.
