What’s your Lee Enfield Holy Grail?

[Brit plumber]

I got this rifle about 20 years ago here on Vancouver Island.
I think I paid about $300.00 for it back then. To date it is the only one like it I have seen but on the Island the number of Milsurps available is a bit limited.
I did at one point consider selling it…for about half a second but dismissed the thought as just plain foolishness.
As for photos OK here you go;

I've got a Unissued M47C too, Serial No.BK1632, very close to your own, there must have been a batch of BK numbered guns that were unissued.
