1942 D4 7j serial number info

Hi
Can you give me advice where to find serial number in these early D4 tractors. Found tractor which I suppose is maybe 1940 -- 1945 model. Tractor is yellow but original color is army green. It is possible that tractor is old war machine and sold to Finland when army after war was trading surplus machines.

You won't access the serial no on the rear with that winch fitted .
The rear plate may have been removed to give a flat surface for the winch to bolt to .
However the number should be stamped direct into the rear housing. Visible if you have the winch off.
Also there should be a serial plate on the engine block. Sort of behind the pilot motor clutch controls .
Your tractor looks like a 2T series D4. Fitted with a LePlant Choate bulldozer and hydraulics.
Nice find and good luck with your tractor.

Thanks for information Andrew
I have to work more to find serial nr.
