well after looking up the serial number date and some light reading your crawler was built between 1947-48 and it was under the oliver name then so it was painted green, technically the dark green you would see in pre 1950 olivers. my HG is in the same boat, it was yellow when i bought it but had green paint under the yellow but the tractor is technically a first year hg which means it should be wearing the cletrac orange so my HG has had a few paint jobs in its life.
