Does it also have another hole below the slot but above the derailleur? If it's the dropout for the "Porta Catena" (chain holder) it should have two.

John Barron recently posted a clever and useful photo that shows an old 1010 (long slot) dropout with the hole for the 50s Sport derailleur, resting on the instructions for the Porta Catena, which attaches to the newer 1010b (short slot) dropout. See: (Thanks John)
