Holy (Hole-y) Paramount!
Greetings!
I've been lucky enough to acquire a near-mint, full Dura-Ace, '88 Waterford Schwinn Paramount ($600 on Craigslist! Don't hate!) this week as my first
entry into geared road biking.
I'm curious as to why there are holes in the back (towards the headtube) of
the seat stay- 2 parallel about an inch from the top tube, and 2 parallel about
1-2" from the rear dropouts-They do not go through to the other side-
I was quite alarmed someone may have done a hack-job fender or rack mount,
but I've seen them in pics of other Paramounts of the same era.
Also, what is the small screw-shaped fixture on the inside of the right seat stay (1-2" above the chain) used for?

No photos? Without them I'm guessing the holes are vent holes used when the frame is brazed to allow hot gases to escape from inside the tube. The fitting you describe sounds like a chain hook - somewhere to place the chain up temporarily out of the way when removing or replacing the rear wheel. Please post photos, I love looking at these bikes!

The little screw is a chain hanger. When removing the rear wheel, you can catch the chain on the screw to keep it from totally sagging everywhere. Actually kind of a useless feature but a lot of bikes have them.
The holes may be vent holes from the brazing process (hot tubes = hot, expanding air inside that needs somewhere to go). But without pics, I'm guessing here.

No, no, no. Those holes are symptomatic of advanced form of filiform corrosion, fatigue cracking and spalling. They are a sure sign this frame is about to die on you. That's why you got it for such a good price - the frame is toast. The "screw shaped" feature is probably tried to use a plug to fill one of the holes.
Send it to me. I promise to preserve and protect what's left of that frame.
