Here's one fitted to my A10. It's been on there for a few years, a good rack and no sign of any rust on the chrome to date.
I had a brilliant rack on my A10 in mid 60s. I was telescopic, the rear upright on the end slid in and out and various extended positions was fixed with split pins each side held by chains (can just be seen in enlargement at arrow). Never seen one since.
The house in the background of the photo of my A10 was a post war prefab where my girlfriend (now wife) lived with her parents. These prefabricated houses were shipped from the USA as emergency housing after Plymouth and other towns and cities suffered heavy bomb damage during the blitz.
