SMLE Mag question.

Sorry if this is a dumb or frequent question but I am
Looking to list a few smle mags on EE and dont want to mis-represent them so any help is appreciated.

I am very much a milsurp noob.


They both are stamped 4 on the bottom rear and "3" on the follower.

Type 4 mag with the correct type 3 follower both for the No1 MkIII or MkIII* SMLE
Looks like the one on the left was made by RSAF Enfield (but could be wrong, hard to tell) the other with MA stamped on it by Lithgow.
