Yes, I know that Dr.Janos Tandari died.
I don't know, who is the owner of front cover regulations book YU Rally 77.
I think full results are in the archives of the main news-agency(then Yugoslavia). This agency sent those results to APN, TASS etc...
Any chance to check it ?
Maybe I can try in E-mail ?
Do you know which Serbian news agency own the old archives of the earlier Yugoslavian agencies ?
Just an idea, maybe I am too optimistic
