The superb 1/43 diecast French Renault-Saviem TP3 MB39 trans-Sahara canvas back desert truck from 1975.
I can't be 100% certain, but I'm pretty sure that this model has been made by IXO for this French truck part work collection.
The truck measures 4 1/2" (113mm) in length, is presented in a carded blister, & is new, mint & sealed.
