I know two more non championship races: Gran Premio Shell, raced on April 21, 1963 and Gran Premio Dino Ferrari, on September 16, 1979.
I have just discovered another race, 1. Coppa d'Europa F.1, scheduled on September 25, 1977. I don't know if this GP was really raced or if it was canceled; however I found it on Autosprint issued the previous week. This means that maybe this race was canceled few days before it scheduled date or it was raced and son forgotten.
I have also something to add to 1963 GP.

If you wonder why Lotus are named M.11, M.24 and M.25, I think that M. means Modello (= model).
This is my result, found on Autosprint 38/1977 page 17, compared to Quentin Cloud's website (and also on Autosprint 18/1984 page 58) :
- Jim Clark (Lotus 25 BRM), 50 laps (250,850 km) 1.34'07"4 - 159.907 km/h
- Jo Siffert (Lotus BRM) 1.35'23"8 (+ 1'16"4) (1.35'33"0 (+ 1'25"6) according to Quentin Cloud)

- Jo Schlesser (Brabham Ford) +1'41"2 (1 lap according to Quentin Cloud)
