Michał, part of the responsibilities of collectors is to help others, especially novice collectors determine whether an artifact is genuine or not. Many peapole read this forum in search for information and help. I am an of an opinion that without a hard evidence it is really hard to say the flash is a fake.
Apart form obvious fakes itís better not to give final judgements on any item to avoid confusion. What if the flash is genuine and someone, who reads our chat believs you and Tony and trashes it? This is what I am talking about.
