Can anyone help me sort out whether this was a dream or not? Beside the commonly seen Campag dropout drilled for the two hole "Porta catena", did they also make a single hole dropout and matching chain carrier, or did I only see that in a dream.

Not so subtle plug, but if any one needs a standard two hole variant, with the modified gear lever, I have a NOS one, with packet and instructions. $45.

Chuck, any idea what year this was first made and how long it ran for?
