I sent & received several messages with the seller of the one that sold for £204.99. I asked about any markings and he said he nothing about anything military so didn't know what to look for. I questioned how it knew what it was called and how he knew it was a scarce piece and his reply was "Yes you are right I listed this as scarce but only because thats what I have been informed I didn't even have any idea what it was until I asked and this is what I was told it was but they didn't say anything about a name or anything so I'm sorry for my genuine ignorance to this item but only put it on here just to see if it would get any bids." I then asked how he obtained it and he said "I know you said I listed it under original in the listing but didn't even realise I had done that, as you can see I only just opened my account and not really sure what I am doing and still trying to find my way around ebay. I found this among my nanna's belongings, it belonged to my grandad who died many years ago and we are having a clear out as she is moving into a home but she doesn't remember where he got it from or how." So as you say, someone paid mucho money just for a piece of steel and, of course, a spring.....
