Hi Ken
As they were built about 4 years ago I'm a little hazy on the details but as far as I can remember the one with the Duvall windsheild used a Replicas & Minatures resin body & grille shell - the grille insert was from the MCG detail set. I think the flathead was from the Revell-Monogram 50 Ford P/U with R&M Offenhauser heads.
Pretty much the same goes for the metallic green lo-boy - I think the chopped grille was also from MCG and the tyres/Offy heads/beehive oil filter/air filters were from R&M.
Hope that helps a bit.
Thanks
Andy
