What are these cantilever brakes?

[danbe]

Firstly apologies if these belong in the pre 98 section I have no idea what year they are or what they are


Any idea what these are? They're very similar to Paul Stoplight MCs & Avid tri aligns only they're not..







Any help/info is much appreciated, thank you
