TBH, the information is all there. Yes, quite a bit in the books can be contradictory, but a lot of it is because someone has made an assumption based on dodgy info which then becomes fact as it's repeated over and over. For example, many captions of photos DD744 wearing the silver scheme say it's a PR.II because it became one. The earliest one I know of with photos of it say it later became a PR.II and so people assume it is a PR.II without looking at the actual photo itself.
People just need to do the research themselves. It's rewarding in and of itself. I can see why some people get so wrapped up in it and just don't want to do whiffery. The more hardcore say it's because whiffery screws reality, or cheapens it. One guy I overheard at 'udderfield Show a few years back said it was "insulting the dead"... I just think he's an unimaginative f***tard.
