If a Diana version is advertised in 1930 and another version doesn't show up in the catalogs until 1935: you've got the answer of who came first. The answers rarely come in one big box with a bow tied on top. The big picture is always made up of little things that bring the whole into focus. One of the hardest things for most folks is tossing away any preconceived ideas and bias and letting the facts tell the story instead of trying to make the facts fit the story you want.
