I am glad you like it!
It is this item: Tamiya Toyota Bruiser 4x4 driver #54416
I had to add the white visor and his goggle. The visor is made out of the plastic inlay of this:

Below the golden chocolate balls I cut out a part and glued it to the helmet with Shoegoo. The goggle is made out of the same package xD but I used the clear upper part. You can also use any thin lexan. Cut out a goggle shape in the right size, paint the edges black and glue it to the helmet. I searched the net for good pics of Jim. For example this one:

As colours I used:
Flat Flesh XF-15 for the face,
White PS-1 for the visor,
Metallic Blue PS-16 for his eyes,
Black PS-5 for the inner helmet cushion (on both sides of the face),
Silver PS-12 for the press buttons of the visor and the rivets for the chin strap
and a 70% / 30% mix of PS-16 Metallic Blue and PS-5 Black for the helmet colour.
