That fitting kit is the saddle support a few generations ago the Carradice made. It was soon discontinued, I had one, and it just disintegrated one day with a fairly full bag. I can't even recall now how it goes together, but you can easily take the bag off when you leave the bike, which is a great idea, but the execution of it was pants.
