Here there is my try at this old Esci model, reissued by Italeri. It has some inaccuracies, but it is a interesting model.
I needed a Dodge truck for my wargaming, but buying just the kit of a truck is always a bit dull, and sometimes quite expensive. When I saw the version with anti-tank "power" for a good price, I didn't think twice. I thought that it was a new tooling by Italeri, but no, it is old school Esci.
