I think they came over from Europe, and yes, they are good for collecting. All of them are matching and the 370 is a great price for a matching, full, original Lee Enfield. Although, if these did come from Europe, they will have the new UN markings that they are trying to force on everyone. But these can be seen as a legitimate part of the rifles history.
I am thinking of picking one up, as I don't have a British example of a No.4 yet.
