Yours looks great. I noticed that you added spark plug wires and the copper tube through which they passed. If any, what other details did you add?
I'm currently wrapping up the interior and engine compartment on the one that I'm building.
Where did you get, or who makes the spare fuel barrel stowed on the back? That's an after market part I've been looking for without success.
First of all thanks your comment!
I compiled almost two pages of notes covering the enhancements/additions to this model. Note that I did not scale things out so features are imprecise. In other words I winged it, but the effect is there. I found in my research many variations among vehicles, so I had to decide what was most probable for the tank I was building. For example the tube that the plug wires go through can be seen in different styles. One of them I found was longer, and curved downward with a flair. The one I opted for was simpler and easier.
The spare fuel barrel was difficult because I could not find any good photos of one. At best they are blurry and reveal almost no detail or markings. I even googled French fuel containers/barrels of the period and I found everything but what I was looking for. Anyway, the drum was made from a piece of PVC pipe used for landscape irrigation, some sheet styrene, lead, brass wire, and a couple of bits from the spares boxes. Once again I approximated the size based on those poor photos I found. The small vent cap was a photo etch piece from the spares and the fill cap was made from 1/35 German tank driving light cap. All I did was fill the slit and filed down the outer circumference into a hex shape.
Hope this helps, and if you have more questions, feel free to ask.
