I have held off comment on this one, as it was an ongoing auction. I think the rifle is the real deal. In the serial number list I keep, this rifle is ONE digit off a confirmed sniper in a well known (deceased) Enfield author collection.(since sold off). I would not dismiss the correctness of the scope and mount, either. The story I'm not to sure about, seems a bit contrived to me, but I have learned enough about Enfields to not make hard and fast rules about anything. (For example, the two off modified scopes that Nigel proved were the real deal).
Buy the rifle, not the story.
(I see that the kit sold for $4,000)
