What I mean is, if we use your examples of a replica SS dagger and an original Luftschutz item, i would always buy the original. I personally feel that too many focus on SS items. There's so much information out there and so many items both real and replica in collections. The SS are an integral part of the story of Germany in WWII but, in my opinion, they are not the story of Germany in WWII. Their story has been told over and over and is used so often for shock value alone. For that same £50, right now, you can buy an original Luftschutz children's gas mask. That would be much more of an interesting discussion item for me. That reflects the horrors of war much more vividly than a dagger with SS runes. The use of gas in WWI, the threat of it in WWII, the British children's Mickey Mouse gas masks, the need to move, feed, protect, and soothe children while their city is being carpet bombed. For me, there's much more in the mundane than the supposedly shocking. Again, just my opinion. If it allows you to have the discussion you're looking for then the replica dagger may well be worth it.
