Just some comparative photos below, showing base plate and front axle supports differences. The later supports were shortened. The early base plate for 139am shows the ridges whereas the later 675 is flat with larger lettering + number 170, which is the later number for the civilian Ford Fordor, but remained there for the Military version too. No. 675 was sold in a plain yellow box with Dinky Toys brand name in red on all surfaces. The end flaps say: 'Army Staff Car'.
