"The Lost Olympiad"

I have a copy of that book. I can check for you after I get home from work unless someone else beats me to it in the meantime.

Just checked the Lost Olympiad book for you. There are two Horowitz games and 3 Danielsson games in it, but none are the one you are after.

I did a little hunting for the game. There is a reference to it in the games database at www.chessbites.com but unfortunately it is a stub entry only; the games details and result are listed but no moves are in the database.
www.chessgames.com is not opening for me right now so I can't tell you if it is there.
Have not been able to find it in any of the other databases I have checked so far. Looks like it will take some hunting down.
I am hoping someone has a copy of W. H. Cozens' book and, if so, can tell me if the score for IA Horowitz' draw vs Gosta Danielsson is given. If it is given in the book and it's possible, can the book owner scan or photograph (or copy by hand) that game score?
