Ferguson Club Information Exchange

I have recently purchased my first tractor, a Ferguson 35 grey gold which was first registered on 31st Dec 1957.
I have been trying to source the correct[authentic] paint and the right colour spec.
I have searched the internet but there seems to be several different shades.....Can anyone help me please

I may be late with the replay but this site is needing some input so

Just done my Fe 35 and used vapormatic engine gold enamel use paint thinner not gunwash and spray it on in very light coats leaving coats to go touch dry , the gray you want is not the same as a te20 , its Ferguson light gray for a fe 35 tinwork. and it very important to use a good primer first

you wont get a exact match to the old paint as paint had lead in it back then which gave a certain tint to the paint
