From what i recall, There were episodes beyond the initial airing but after Galaxy and BSB (British Satellite Broadcasting) merged with Sky under BSkyB plus the complaints of the show itself, BSkyB shelved them indefinitely
I kid you not I think I read somewhere the script for one of the episodes...
It might have been a fanmade thing, but if I recall correctly it was about Adolf's brother coming to visit, and Adolf and Eva (who was apparently going to be played by a different person in than in the pilot) got rid of him by giving him fake paintings...
I also heard that Stalin was going to be in the Christmas special
