I am looking to change the “L shape” battle sight on my 1942 Savage to one of the better ladder styles. I realize that the Mk1 micrometer is best, but for what I use mine for I think I could save a few bucks on eBay and go with the later-style ladder sights.
Could someone enlighten me on the difference between the sights marked “MkII” and “Mk3”? Both seem to be readily available and at a lower price point than the Mk1. Thanks. Photo to assist.

As far as I know, the only difference between the two pictured is that the Mk III has a curved lever. Keep in mind though that both those rear sights are English. If you want your Savage to be correct, you'd need to get a S marked one.
 
Seems to be chiefly in the design of the slide, which has a pointer to the graduations instead of a lubber line. The two Mk 3's I've got here also have a smaller battle sight aperture. Slide stop pin is on the other side. I've also got a Mk 4 with the small battle sight and a pointer-slide stamped 'Mk III' and a Mk 4 with the large battle sight and a pointer slide stamped 'Mk II'. Go figure. The best we can say at the moment is that the construction of the Mk II and Mk III slides differs slightly. I've also got a Mk 4 with a lubber-line slide constructed in the Mk III style.
The C Mk 4 sight (stamped C Mk 3 on the leaf, everyone keeping up?) has a full-width base which eliminated the need for the separate bushing on the British ones. It is not clear to me whether the base was brazed on separately, but this design also allowed the battle sight to be much more robust (like the one on the milled sight) rather than bent metal formed from stamping the leaf on the British ones.
All the sliding sights are less robust than the milled one, and one dealer I regularly see has a bucket full of them, all with something in them broken, usually the catch.
The whole thing calls for a photo essay.
 
And it might have slop/backlash in the threads ... I see plenty that do ... often go through several to find a good one.
 
Mk VII; is there a difference between the two sliding styles as far as milled vs stamped steel construction? Or are they both completely stamped? I thought I read somewhere that some of them are a milled/stamped hybrid.

Save a "few" bucks?????????? HERESY I SAY.

The sight you have now is a very good sight and it's correct for your rifle. The sights in your picture aren't much better and not as strong, not that you're going to have to worry.

This just means you NEED ANOTHER No4 MkI or MkI* with a MKI rear sight. You just don't have your priorities straight.

I see MkI rear sights at most of the gun shows I go to for around $65.

Both sights pictured in Fig 15 are Brits. The different between these two is in the slide detail and the retaining catch. If you use one of these as a replacement you need a small spacer for the traverse pin. The Canadian version of these sights is a "hybrid"..it has a milled base (no spacer required) and a stamped ladder. The Brit Mk1 sight was used on many FTR'd rifles....it's a good option to replace the 300/600 battle aperture. Cost of this sight is approx $65 whereas the "S" marked savage is considerable more. You'd have to make the choice ....functionality or correctness?

When you say Canadian version, are you talking about the later ones marked “CMk3”? Or are you saying any Long Branch sliding sight is the hybrid? These milled hybrid type seem like they would be ideal for me, unless of course they end up being just as expensive as a Mk1...
 
Canadian version. Long Branch produced the Mk11 and Mk111 with a milled base for 1942 - 1945 Enflied and the CMK3 for the post war Enfields. These are much better constructed than the Brit models. You should be able to get into one of these for less than a MK1 Savage.

Proper Gunnutz, that bit.
 
Just a brief question on the Singer micrometer adjusted sight. I noticed one on eBay that came with a spring and plunger. I have been trying to figure out exactly where this attaches and what its function is. This is not the pivot pin at the base of the sight, which I believe is held on by a small pin on one side. This has got me stumped

The spring and plunger keep the sight locked rigidly in place when either folded up or down. All the styles of sights use this. Hope that helps.
 
When you remove the rear sight axle to change out the rear sight, that plunger will jump right up at you from it's hole in the receiver rear bridge, directly under the rear sight.

Thanks That makes sense. I haven;t had an Enfield since the '70s and I haven't received the one I bought yet. Just going by pictures on the internet. What keeps it down when the sight is up. Is it right under the pivot pin or axle ?
