I can assuredly say (for what it's worth) that the Cromwell was on that pedestal in 1988 or 89 when I walked by. If I read the plaque then, I don't recall what it said. I also don't think it's there anymore because the photo is of a Cromwell at the IDF Armour Museum in Latrun in 2005, and it looks like the same plaque is now on the mantlet of the tank. Here's one of the plaque on the tank, but I can't see it well enough to read it (outside of it saying "Cromwell Tank, produced in Britain.) Maybe our resident shiryonairim can shed more light on the question. There is a 2nd Cromwell there, painted as a British 7th Armoured Div. tank.
