I have some of the sales doc’s for the device somewhere, i will try and look them out
A few of the large fleets used the Hope device, but I wouldn’t imagine that many ‘one man bands’ bothered to specify them.

The firm I worked for in the 50/60s, tried a similar device, Anti Jacknife Ram it was fitted to the tractor unit on a swivel type king pin, the trailers were fitted with the eye that it connected to. They never caught on, they were difficult to connect up if the trailer wasnt perfectley level,
