Could that be because we just got on and did it, without having to tell the world what we were doing??!Have you tried contacting things like War or Military Museums? Sometimes there are stange things kept in the archives, I once found the words to God save the King scored in Hindi for Indian orchestra!
There might be something about the UK land army girls, but not sure if that would be appropriate.
There are plenty of talented writers out there, why not get someone to create a new one? A request on here might net you a whole bundle of fun.
