Sheldon, In addition to the red labels that most of us are familiar with Fiamme also made a red label track rim. They were narrower and the braking surface was angled inward. Also, red labels were reasonably light; maybe 360 grams.
Jamie, I can't believe I corrected Sheldon Brown, Swan.

Sheldon Brown replied: Those look really cool, but they aren't really track wheels. The Fiamme red label was a heavy-duty road rim, and these 36 spoke wheels would certainly be extremely bomb-resistant.
