After watching some videos of SMLEs in action, I had the urge to mess with mine a bit...it's been a long time since I fooled with it. What got my attention was the magazine cutoff. Since I've never fired the thing, and the rifle is in great condition, I figured it would work just fine. I mean really, just grab it and push it in, and pull it out.
Nope. The cutoff was pushed in, and would not budge...what the heck? I dropped the magazine and the cutoff still would not swing out. I pondered this for a couple of days, looked up some schematics, and could only think it was rusted in place. So I went at again. Removing the mag, I discovered that with my thumb in the breech I could push the cutoff out. Then the bulb lit! The cutoff has to be depressed slightly before it can be pulled out. That little bit of flat steel on top of the cutoff has to clear the side of the receiver. I feel quite accomplished. But, and I defer to the experts, is this how the cutoff properly works? I know, rookie.....

Had never thought about it. Its an automatic action when you open the cut-off with your right thumb. |

i had the same thought but its an accurate description of the movement to have it function , im sure basic training back then covered it but since these were dispensed with -mostly- in 1915 i guess its not a common thought these days ,

Howdy 🤠y’all That little piece of flat steel steel (wedge) is called the (cut-off catch) & yep by slightly depressing the cut-off at the thumb-piece it will (should open out wards,if it swings freely in & outward’s then something is wrong as in (worn out etc).Cheer’s.

I have since noticed that the "wedge" is well polished on its leading edged and can well imagine that over time with enough wear it will no longer stay in place.
Also interesting is the little peep hole. I guess that's there so that you can see if there are rounds in the magazine? Seems a bit silly.

What I find interesting about the cut-off is an apparent change in purpose. Initially, to hold the magazine in reserve while single loading. Eliminated during 1915 as a manufacturing shortcut. However, reinstated during the 1920s following the WW I appreciation of rapid magazine fire. Obviously, its purpose was then a safety feature.

Howdy y’all; The little peep hole was used in the jig setup’s when machining the cut-off’s to hold them in place. The only cut-off not to have the (peep hole) is the MKV type. Cheer’s.

Yep interesting for sure as safety feature. Both HMS & RAN both had a tradition of using them. The RAN used & (kepted) the volley sight & (cut-off) setup MKIII’s well into WW2 on ships & range target practice etc. Cheer’s.
