Hi, Martti...

Very interesting. I have to say though, that clearly from many photos available, Bf109E-1s and E-3s had open, ducted spinners. Perhaps they were all supposed to be the same, but I wouldn't say it was the case in practice. Perhaps they were the same, but could be 'capped' if necessary, but that raises the question as to why there were two different types of spinner in the first place. Perhaps someone more knowledgeable on this subject than myself could explain...?
