English GP ace Ireland had success with the "Team Rosebud" Lotus Mk.19 in the Under two liter class.  The Coventry-
Climax powered 1963cc. car was lighter and more powerful than its Porsche rivals.  The car used the smaller engine because its 2.5 liter mill blew up at the Portland, OR, "Rose Cup" pro event on June 17, 1962.

Driver Pete Lovely was top qualifier at Portland before the blowup, and had won at Laguna Seca the weekend before in the car.
