Bedford QLC 6 tonner heavy-truck - tractor

[Panzerserra]

Gents, hi...

I´m collecting material for the construction of model kit of this truck:
Bedford QLC 6 toner



I have doubts about the system of the trailer hitch in the truck (see arrow)...



I know that:

" A rather different variation of the theme was provided by the Bedford QLC 4 x 4 - 2 General Service Lorry. This consisted of a standard QL four-wheel drive chassis to which was permanently coupled a GS semi-trailer with tilt cover. The Ball-type coupling beiong directly over teh QL rear axel. A small cargo body of 1 ton capacity was fitted" .

The 1 ton cargo body was a drop side and the fitting a ball type coupling.

Please, someone had a picture or drawing of details of this system...


Thanks in advance....
