Neat car!
There's an interesting story associated with my '61 Bonneville...the original owner had previously owned a 1959 Bonneville, also painted Mandalay Red and with Tri-Power. When he bought this '61 he special ordered it painted the same Mandalay Red, and added 1959 Tri-Power emblems to the front fenders. Since your car is from California it's not the same one, but it looks like it could be.
