I upgraded this old Tamiya's kit with Blast Model tarpaulin, resin wheels w/chains from Black Dog set, Dragon's lights, tools, side cases and front bumper (I' don't know the name of this round part), some resin jerry cans and other stuff from my spare box. The machine gun was replace for RB Model metal one.
The base is 21x17cm. It's quite good - not to big and not too small, just properly for the part of the building (MK 35 product), some ground and 2 figures from Alpine range. The majority of the details were prepared by myself but e.g. telegraphic pole is from Verlinden set and the cat is from Tamiya.
To resume, building the kits from the beginning is much more nicer than rebuilding but those old kits are delicious bases to play them with. I have another kit to rebuild and this will be an old Chevrolet, so keep your fingers crossed for me!
