Have these two rear sights in my parts bin, are either of them correct for a No.4 Mk1*? Thinking of returning my ‘43 Longbranch sporter to irons, when I originally picked it up it had the 300/600y L shaped battle sight but I like the smaller appeture sight on the ladder sights.

42-43 LB should have Mk 2 backsight which is a plain flip up L shaped dual aperture (not a ladder).

That would be the one you describe as coming with the rifle when you got it.

looks like this http s://www.thegunner.net/ccp8/Item/Enfield_Mk2_rearsight

You could retrofit with a rear sight w/ladder marked C Mk III (or C Mk 3) which LB started to use in 43-44. Early ones had a small aperture, later ones the larger aperture.

The Mk III you have was for the British manufactured rifles, but is basically the same as the Canadian marked one. I'd just throw that one on it as it is period correct.

Thanks, yeah the original mk2 isn’t my favourite anyway. Seeing as neither of the ladder sights I have are LB marked and the gun is sporterized, I’m not all that concerned with it being period correct. I take the fine adjustment of the micrometer is a step up from the mk3? Whichever one I don’t use will go on a friends No.4 I’m cleaning up for him.

The micrometer sight is actually earlier 41-42 Mk1, but they went to the simple Mk2 (Long Branch and Savage) then stamped Mk3 (Brit rifles) due to getting them out the door fast during that part of the war.

FTR'ed and post war rifles a lot went back to the Mk1 sight as it was better quality - milled vs stamped, micrometer adjustment etc.
 
I have about a dozen different ladder sights in my parts bins.

the micrometer sight was the original, replaced with the war time expedient 300/600 flip sight. Then the MkII and MkIII ladder with slider some were marked Mk3 and CMk3

some of the sliding ladder sights uses a solid base like the 300/600 flip while others were just sheet metal with a small spacer on the right side. The one you have is the previous type, which I find more desirable.

in your case uses whichever sight you prefer

Good info, thanks. Upon closer inspection the mk3 I have is LB and C^ stamped, hard to tell what the mark is above the 53 on the micrometer sight. Guess I’m keeping both and my buddy is getting the 300/600 battle sight.

In my spares I have the same LB marked and stamped leaf as your MK3, unfortunately the backsight slide I have for it is missing the slide catch, pin and spring. Marstar used to sell the complete Mk3 sight as you have but they are out of stock ATM.

Probably a B. BSA inspection mark
