Obscure F3 race - where and when?

If the links work, it should lead to a site with photos of former motorcycle rider and sometimes race drive Sven-Olov "Esso" Gunnarsson.  Question is if someone can identify the race and, even better, if someone can provide a list of starters and/or results.

Apart from Esso Gunnarsson and his Cooper T59, Yngve Rosqvist is also seen in one of the photos in a Cooper T76, which should lead us to 1965.  The other cars, apart from a Lola Mk 5 and a Lotus 18, are clearly Melkus or similar, which means Eastern Europe.  In one of the photos one can see signs with the word "ulje", which ought to mean "oil", but which language?  It is not Polish or Czech, so maybe we are in Serbia or Croatia?  Any ideas?

Thanks Regazzoni,

Now at least we have an idea about the country.  I did check the site you mention before posting and also found that it was lacking in information regarding the Yugoslavian races.  Regarding the Swedish racers, I would guess that they tried to put in two-three races on consequtive weekends, say in DDR and West Germany, on a tour like this (unless they combined it with a family holiday on the Adriatic coast).

Which could lead us to the Adriatic Grand Prix in June 1965 won by Manfred Mohr in a Brabham BT15.  Anyone out there who has results from this race?

Thanks Regazzoni,

Both Rosqvist and Gunnarsson raced at Roskilde Ring in Denmark the weekend before the Opatija race and Rosqvist also took part at Avus the weekend after.

Based on the different cars and the position of the sun, we must be looking at photos of two different races within that weekend. My guess is the fourth photo is a heat race, and the third race is the final, held late in the day.

Looks very like Preluk ( Opatija )  to me - sorry it's taken 4.5 years to answer  

Preluk indeed
