These can be found at some Barnes & Noble stores and possible online but I have struck out so far. Good luck!
This was in a recent eBay auction and since I’m American, I had no idea there was such a thing as a Sooty or a Sweep. I am a bit more educated now. It was a popular kids show in the UK in the 70s. Sooty is the bear and Sweep is the dog. There is also a rare Marx made friction toy out there. And I even found a YouTube video of the show for you (sans scooter . . . sigh):
