By 1987 they were using Shimano forged dropouts (see picture of my '87 dropouts below), and I suspect that's what was used on this bike. The seller says they're Campy, though, so maybe they are. I find it curious that there are eyelets on the dropouts; they may have been ordered by the original purchaser.

Neither the 1985 catalog picture nor the 1986 catalog picture show eyelets on the dropouts.
