Long Branch serial number listing

[BurtonP]

First post for me.
My first Lee Enfield was/is a 1945 Long Branch No4 Mk1*
SN 84L2731 with matching bolt and receiver. No SN on the mag, the blueing is different, so replacement?
Walnut stock, but is an unsporterized "Surrey" so mostly replacement.
Ribbed top wood replacement.
Steel butt plate.

Hope it's not already in the database! Cheers.
