This is purely between the two of us, so keep it quiet, but the patent on the mud brick has expired, so licensing may pose problems, although her Maj is quite keen that you pay something, she say's you've already had Light Bulbs & Jet Engines for free (actually she had quite a long list but I distracted her by telling her that one of the Corgi's had managed to get out and was humping a guards leg). Although, she did say, as a sweeter, that she'd be happy to have you as subjects again providing you get out the tea-pots, quid pro quo and all that. I suppose you could translate it as Bricks & Tea offor Tax & Coolness. Oh, and I suggested that you get the ginger tosser back.... for free.
