BTW, late sixties/early seventies Schwinn Paramount road models (P13, P10, P15) came standard with oval fork blades. My '72 P15 has Imperial Oval blades. Schwinn would build bikes to customers' specs as long as the engineering department reviewed the customers' requirements and approved them as not compromising safety/structural integrity, so it's not a surprise that some road Paramounts would have been built with round fork blades.
