No, earlier Record bottom brackets used 11 1/4" balls on each side. I don't have a post-1990 Campagnolo bottom bracket to check, but I do have a Zeus 2000 titanium bottom bracket that uses 14 7/32" balls on each side, so I don't find that implausible.
2. 109 mm axis lenght with 1 or 2 chain rings?
I haven't tried C-Record with a single ring.
But the 109mm SP and SS spindles are noted to be the same.
3. 70-SS with 109 mm and 14-3/16?
I do have a C-Record 68-SS bottom bracket that measure 109mm and uses 14 3/16" balls.
4. I've seen 68-SP without "c", this is not listed in the table
That was on the previous page:
