The early Wingets looked like these in the 1950's when the Barford 100 came out.
I guess Winget copied the idea. Most manufacturers seemed to " share " design features at the time.
As Andy says above, A-B Hire was an offshoot/subsidiary of Aveling Barford until Leyland bought Aveling Barford in 1968.
Despite being profitable,
Leyland sold A-B hire, which became Abex, which was a bad move like so many decisions made by Leyland executives who hadn't a clue about Engineering.
A-B Hire was a great way of putting A-B machines in the field, and having just joined Aveling Barford the same year, I remember the consternation in Sales that a very profitable captive market had been dumped.
