A silly Jeep question

Well Geoff, I can say that I have heard both pronounciations, and the answer to Tony must be that Chris is right so far as North America is concerned and no doubt elsewhere but it has also been pronounced differently where it might have caused offence.

I should add that in the pre-war period the War Department and DND both dithered on "s" or "z" in "mechanisation" or "mechanization".
