Information needed for a SMLE Lee Enfield magazine

6 Attachment(s)

Last week I stumbled across a .303 Lee Enfield Magazine.
I did a little research and found out that the magazine is an early SMLE magazine, dating from around 1906/07. Magazine was updated from version 1 to have a hinged right front feed lip that should be rotated forward out of the way when removing the follower to support cleaning. It is marked with a "2" on the back of the box and also has other stamps that I can hardly read even with a magnifying glass. I don't want to remove the spine patina because I want to leave it as is. My research has shown me that the magazine is a #1, version 2 magazine servicing a Lee Enfield Mk3 rifle.
I hope I am correct in my research and if not please do not hesitate to correct my information. Being unfamiliar with Lee Enfields, their parts and magazines, just wondering if this is still a collectible item and if yes, what could be the value of it. Thanks in advance. Your help is very much appreciated.

Looks like its from a MLE. ie Long Lee.

Which would be ok with the 1906 date, as well.

Thanks for your info. Do you maybe know by chance if this magazine has a collectible value? Thanks.

No more than $50 really.
A pristine one might sell for $75.

Thanks @dogmatix
