Hanno, I meant to ask instead of

What Ford chassis did the Mark IV use as it was rear-engined?

What Ford Model Number components did the Mark IV use as it was rear engined?

I discounted C191QRF and succesors as they were parts, not complete vehicles prima facie . There was indeed apparently a S/M Contract series for components and parts, in the S/M 3001+ series I seem to remember as the 1001+ series was for armoured vehicles et at. The soft-skins & motorcycles series started at S/M 2001, although the first that I know of was S/M 2002, then it jumped to the 6001+ series.
