Reader Anthony Byrd spotted this lovely little Parilla at the AHRMA Vintage races held at Willow Springs last Saturday. The number plate on the front reads 515, but the immaculate machine is otherwise a puzzle. (A further clue: it was also spotted at the Venice Vintage Rally held in LA the weekend before.) Parilla was a Milanese marque known for its ‘High Cam’ engines, and I’m guessing this one is a mid 1950s model of around 175cc, possibly with non-standard front forks. Can anyone clear up this mystery?
