There's all kinds of talk about Super Record hubs, but I've never so much as seen a picture of a set. They supposedly have titanium axles. I believe there may have been some prototype modeks made but no production versions. There really aren't Nuovo Record hubs either, just Record.

What you have are Record hubs. Flat lever would indicate pre-CPSC (~1977). The cone/nut hardware holding things together will have a date stamp 99% of the time, I have several with no date though.
