[George Moore]

Looking again at the stuff Darian posted and sent, am I correct in saying that there were two types of 6 wheeled trailer, one rated at 8 ton, the other 7 1/2 ton ???

What appears to me is the basic similar layout of treadways, but the bogie and construction of the main frame differed......the 6 ton does not seem to have the pivot arrangement between the front steerable axle and the main longitudinal beam (chassis). The front towing A frame is square on the 8 ton, but made of 1/2 round angle on the 7 1/2 ton.

Revisiting the photos, the keyhole shapes are very clear, as is the detail on the manual drawings when viewed in close up. Something I had missed.

For information, I enclose the Resin kit that I mastered of the 7 1/2 ton trailer.

George.
