1. Does it have a place in a Lee Enfield collection?
I'd suggest, "not in the majority of Enfield collectors collections"
It is a collection of Enfield parts, some other parts and assembled by someone who has never been near an Enfield production line.
Mine are not the best, but they are not too bad. I can think of lots of Enfields I'd rather have but instead of constantly striving for more, sometimes it's good to be satisfied with what one has...
