I'm not entirely sure if they are what you are looking for, but I'm sure can position them a certain way or something

The Hasagawa GMC Fuel Truck in 72nd comes with a guy refueling that could work for any era.
What scale were you planning?

I was [lanning to do it in 1/48,nut maybe ill do a 1/72.

Monogram had some good ground crew figure in some of their 48th scale kits. You could see if anyone has some to part with. Know there were 3 in the P-61 kit that could be adjusted to refuelers and would probably work with the era you are planning.

Nick;

Check for the NATO Ground Crew Set. It has various posed figures including armorers, refuelers etc. Plus it has vehicles for this type of diorama. Verlinden has the necessary accessory of revetment which is where the aircraft is "parked" for protection. If you can find a copy of the Verlinden Way Vol III On plastic Wings it has lots of good ideas for dioramas along this line of thought.

I'll try and find the actual kit number. However it was an ESCI kit then a Hasegawa kits came out. In any case what you want are NATO figures. Little conversion required as the uniform has not changed much in the last 40 years.

Hope this helps.

Cheers;
