Interesting, although I have never heard about this. When searching for aircraft, Israeli Haganah agents learned of the Czech built CS-199, which it's possible these guys could have come across the CS-92, but of course one issue that would most certainly have arisen was supply of engines and parts. Perhaps (if they did get one to Israel) the reason the type was not put into service was because of this. Its feasible since the CS-199s were crated and flown in C-46s from Czechoslovakia to Israel, so one could have ended up in a crate.
An Israeli Me 262? Go with it - it'd make an interesting 'What-if'; you could buy some Israeli decals for the 'Messerschmitt' as the Israeli pilots called the CS-199 and put them on.
