Hi Jacob - he was made by Cherilea (UK producer) - which was formed in 1946. Metal production was phased out by 1961 - plastics being phased in from 1955. So your find was produced between 1946-1961 - so likely made mid-fifties. They aren't plentiful - so a good find.
I don't have an example myself - but a pic shows him originally with green pants (see page 82 of "The Great Book of Hollowcast Figures" by Norman Joplin, 1993 - paperback edition 1999 - published by Cavendish Books).
I usually prefer to make up a mix of Humbrol Gloss enamels - to make a buckskin colour - using Sand/Cream/ and Desert Sand, for pants.
Hope that helps - jb
