Given that Euro-Asia still has a very generous selection of cogs for
these freewheels, and in VG condition they sell (used) for about $200
on ebay, I'd take extra-special care of your campy freewheel. find
someone (or an LBS) that has the campy tool and knows what they're
doing to remove it.
I think these have a titanium body, which lasts and lasts and lasts.
