Please accept my apologies to everyone who has been patiently waiting for the results of this puzzle.
It has taken some time due to the fact that my source for the results of this event were inaccurate and thanks to Richard Fridd who provided me with proof of the true situation.
My photo (from the Orsini/Zagari history on OSCA) did not tie up with the results that rosenbergm posted earlier.
Now I've managed to sort it out with the following solution - each car and the event solved by richard fridd (with his recent adjustments taken in to consideration).

So congratulations Richard, you've just earned 17 points (16 points for the cars and one for the event) which now promotes you to Expert status. Your reference source was 'spot on'!
I'm also awarding 2 points to rosenbergm as he initially guessed the event was in Switzerland and for posting the same list of cars I had initially. Well done to you too.
Far from being put off by the puzzle being quickly solved in the rookie section, I intend to post some more similar puzzles in the future......
