Forestry truck. Help with pictures?

[Paul Y]

Wasn’t sure how to title this but would like to try and replicate the forestry commission marking on Woody.

Found the black shield from searching for a forestry truck on this board but there are the remains of numbers on the roof that I would to copy.

Currently they are painted over with what looks like house paint that is revisiting my best efforts with thinners….

Looks like a 2 a 7 and or maybe a Z.

Can anybody help with a few pictures?

Thanks,

P.
