Subject: [CR]Oddball 60s Campy bottom bracket question

Campy apparently made a run of bottom brackets in the early 60s(?) that had separate races pressed on to the axle ala the later titanium Super Record. My understanding is they used 3/16" balls (ala SR). Does anyone know what year(s) these were produced? I've also run across a picture of a 1 piece bb dust sleeve, embossed Campagnolo, that is dark brown in color and has a texture to it. It almost looks like leather but I'm sure it's not. Does this ring any bells? I can email a picture (off list) if it would help with the ID. If we get this right, it can be added to the "Time Line."
