Custom Saddlery Royal Star?

I did a search and only came up with a few mentions of this model, that it was an older one (the made in Walsall kind) but not much about how it rides or what shape of horse it tends to fit. One thread mentioned that the CS company didn’t seem to know much about it either, being older and no longer made.

I came across one recently in my FB feed, can’t find much about them on the web and there are very few used ones for sale now with it being discontinued. I am on the terrible, impossible unicorn used saddle hunt and while this isn’t what I was looking for, it intrigued me.

Anyone have any info?
