I'm not really aware of much European support for Zionism outside the Balfour declaration in those years. The declaration remained a declaration and pretty soon the Brits flipped their policy and banned Jewish immigration. You had tiny movements of Christians Zionists (Churchill was a Zionist for instance) but I'm not aware of any substantial support they gave. After the war the big immigration waves were actually from Middle Eastern Jews, not from Europe. Jews from Egypt, Morocco, Lebanon, Syria etc etc whose lives became increasingly dangerous. So my main point is its quite unclear if there was any major support for Zionism in the West in those years. Only after the holocaust could you find a majority that supported establishing Israel in the UN.

If you want to dig into this look into where Israel got its weapons from during its war of survival in 48: https://en.wikipedia.org/wiki/Arms_shipments_from_Czechoslov.... From the communists.
