Our frequent correspondent Moshe Roytman notes that the Yiddish-language Unser Express (עונזער עקספרעס) had published an article, 'The Chess Olmypiad', about the 1935 Warsaw Olympiad which included a pen-portrait of some of the players.
Interestingly, they chose to portray William Winter, Tartakover, Najdorf, Fine, and Porat (then, of course, Foerder) -- no doubt due to him being 'Palestine's strongest player'. He is described as a talented young player which 'even the world masters, like Vidmar, Tartakover, and Flohr, could achieve nothing against him'.
A quick search found no games in the databases of Porat playing Vidmar (which is not to say it didn't happen) but certainly he could hold his own -- drawing and winning -- against Tartakover and Flohr.
