SMLE Magazine Variations and Dates of Introduction

[WillSarchet]

@Bindi2, understood. I am building these up from stripped actions - some MkIs and MkIIIs of various submodels. I'll have to fit a magazine to each one anyways so I'd like to make sure it's the right one. All of the MkIII bodies are post 1910 so they are all for MkVII ammunition, and I have both early and late style sights and sight beds for the MkIs.

@Lance, thanks! I will keep an eye out, I'm definitely not going to have all these wrapped up in a month.

Edit - I guess those pictures raise a couple more questions. On my converted magazines, neither has holes for a chain loop. The one that I believe to be an ex-1st type (on the left in each photo, no number visible under the 3) has the remains of the loop on the inside. Would those have been welded over in service or were they tacked up by civilian owners later? Or were some of the 2nd types made without loops? The 3rd/ex 2nd type has a roman numeral "II" in the inside bottom, if that's useful information.
