I`m also working on a 4x2 Transconti, the original model is a Corgi Major-Toys.
An original with an project
The kysor is removed, and the front-axle has been set back a few mm en a new pair of tyres, the cab and chassis are very good models.
Not the spare-tyre, it was original build by Ford
Photo was taken at the former Ford plant in Amsterdam, there was a reunion a couple of years ago.
