Thanks for the comments gents. Yes it is the original Mutant rpg released in 1984 that is set in a more settled world than Mutant Year 0, in fact it is year 109 since the foundation of the Pyri Commonwealth. We had great fun with it back in the day - this is very much a tounge-in-cheek project and great fun.
As for good old uncle Donald Duck, not sure he would last very long, but as stated there is this Swedish anti-hero called Arne Anka (Anders And) - he said "With a fair iron pipe you hit the world with amazement!"! That is probably more suitable.
