Well, the only thing I got correct was the lack of hyphen in the maker's name! As Bill says, the internet will give all sorts of answers, but in the UK we are convinced there was no hyphen, and Georgano backs this up.
Apart from that, I was wrong on all counts. I believed the source of my puzzle, without checking its veracity. It's not the first time, and probably won't be the last. It shows how desperate some of us get when we're looking for new puzzles!
I'm sure that Wendax is correct, and have amended the puzzle title accordingly.
PS Sorry majeko. You keep your point, no problems. I was unintentionally misleading you as you attempted to solve the puzzle.
