Perry do the Sahariana (from Blitzkrieg) cars,Rubicon do nice Chevys et cetera, 3D printing just doesn’t cut it(yet).
The Italian forces were not that successful chasing up the LRDG,so perhaps that’s the explanation for lack of English sources? Derek Robinson wrote a very good fictional account of the Desert Airforce (A Good Clean Fight),SAS,and the Africa Korps trying to catch them,very inspirational ,and a jolly good read (as are all his books). Don’t forget Brigade Ramke and Popski were also swanning about,plenty of room for all sorts of scenarios.
