Well the location seems right for a chassis number, but not sure. If I had to guess someone has stamped the original engine number there, as it doesn't look neat enough to be factory.

Engine is less of a problem. The T222 code is for the D15 236 cu in engine which has been swapped in - no big deal at all as the specifications appear to be identical. There might have been minor variations in things like the sump shape, oil filter size, and so on originally but no big deal.

The problem may be that if you can't get a genuine chassis number off the front frame rail you won't be able to prove it fits any particular wartime sequence which could give registration grief down the line.

Best advice would be to check all cab plates for numbers, and then have a really close look at the front chassis rails. I don't have an e-mail for anyone with a D60 or D15 that I could get an unmolested chassis number image from - sorry.
