1963 Canadian F1 Stebro Mk4

[propracer]

Greetings fellow racers,
I am currently restoring the canadian built Stebro Mk 4 Formula 1 car which was driven to a 7th place finish by it's builder, Peter Broeker, at the 1963 US World Championship Grand Prix held at Watkins Glen.

I am looking for a pic that shows the back end of the car at that event, since Peter elected to modify the engine cover for the car's subsequent entries into European F2 races (no, there never was a Mk5) and then Libre and FB races later on.

There were over 20,000 Canadian fans in attendance at that race, and someone must have shot a pic showing the back end of the car while in the pits or on the track.

Let me know if you can dig up anything related to the Stebro Mk 4. It was race number 21.

Thank you.
Luc
