Hmmm, there's a completed ebay auction (#220232414752) for a Campania ($280+S&H) hi-tensile beast fixie . It looks like the braze-ons are still intact, but that didn't stop plenty of imbeciles from lining up to buy that thing.

Looking at the info from that auction I don't think it would be Hanover on the tubing sticker, but "H. McIver".

Yours is CroMo at least.
