Garth,
Take out the adjusting cup (if not already out) & measure ~it~ for diameter & thread pitch. The Italian cups are significantly bigger; if you have a standard English cup laying around, you could check if it fits the left side...or not..
(Italian is RH thread & British LH).

Item: 70mm shell Bianchi bb.... Frame made in Italy mid 80's Columbus tubing I need to remove the fixed cup. This must be a common problem. I don't want to muck up the threads, but I have no way of knowing which way to turn the fixed cup. You can't see in there to determine which way the threads are running. If I make a mistake I will have damaged the frame. Which way should I remove the fixed cup....Normal counterclockwise or clockwise?
