Thanks for those thoughts, Jose. I'm pretty well convinced that the lack of Christiansen's markings was due to the intention to include them in a future de-luxe kit. As that will have many other additions, not just new decals, I'm sure that producing these for those modellers who have bought the original kit, will not affect WNW in any commercial sense.
There is one other possible reason that the markings were omitted, and that is to do with Christiansen's behaviour when German governor of Holland during the Second World War. He was certainly no angel and I admit that I thought twice about producing them for that reason, but in the end I concluded that his actions during the First World War were significant enough to stand on their own. If people don't want to build a replica of his aircraft for these political reasons, no one is forcing them. It was another time and we all know that time flies like an arrow - and fruit flies like a banana, of course........
