Hi Brian, just to let you know I've had word from Felix. The battered sausage prototype was an expensive failure and basically he's lost his shirt on the project. They couldn't keep the ketchup in the middle from boiling and squirting out of the end when the sausage was deep fried, and the results with HP were little better.
Anyway, he's now working in a crisps factory and sent me a picture of his latest product.
