Are you talking about the Mark I ladder/standard Enfield sight or an after market sight?
I dont know. It has the same stampings as on my enfield and looks well made so I guess its military surplus.
Is there anything that can tell what it is?
When I was messing with it I found that it takes 6 clicks to bring the elevation from 200 to 300 meters and 8 clicks to bring it from 300 to 400.
Is that about right?

Sounds like you have the standard MkI back sight. It would be proper to instal on your Enfield.
As far as the graduation of the clicks, that is something that may be mentioned in Mr. Skinnerton's books. It was not something that the basic Commonwealth soldier was worried about. Range was estimated and dialed in when time permitted. Otherwise, the 300 yard battle sight was used in hurried situations. I crank mine all the way down on my shooter #4mk1, and with my reloads it shoots about 2" high at 100 yards.
I think that graduating the "clicks" would be something you could at the range though.
And, I don't think MJ knows how to use an open sight. Seems that everything he has is scoped!

MJ is a sniper rifle afficianado. I've been looking at his pics here and on two other boards for some time now and he has a bunch of nice ones.
From what I understand since reading "One Shot, One Kill", US 7.62mm sniper rifle/scope(s) are sighted in differently to the average deer rifle... IIRC, dead on at aim for COM for a head shot at 450m, then aim dead on at 800-1000m, and then dead on for COM past 1000m. I might better look back and be sure; I don't have that info handy at the moment. I don't have much info about British and Russian sniper rifles.
I tried the 300yd battlesight on my No.4Mk2 and it seemed all over the place, but then I need to take it out more often. I was shooting PMP's 174gr SP's which I understand are loaded to Mk7 ball spec. With the 200yd setting, I took a 6o'clock hold on a clay bird at 100yds and watched through the aperture as the target appeared to explode. It was a beautiful sight.

Unfortunately the "clicks" on the micrometer sight usually aren't quite precise. Anyway, they certainly don't equal an MOA or any other measurement like that. The only way I can think of to get a precise knowledge of the value of your sight is to clamp the gun in a shooting vise, or fire it from a bench and really take your time... firing a couple of shots at a well defined target at say, 25 yards. Then, raise the sight one click. Fire a few more shots. raise one click... repeat... measure the distance between the centers of each of your groups, then add them together and divide by the total number of groups. Mulitply the resulting value by 4 to get your 1 click at 100 yards MEAN value. Obviously, you could then double or triple this value for 200 and 300 yards.
Which is not to say that this procedure will provide precise adjustments at those distances... realistically, with enough shooting you'll develop a more precise feel for the sights on your gun... But is a starting point.

I posted this on another site a while back:-
I have just set up two sights, one carbine and one rifle, with a vernier calipers. 7 clicks on the carbine sight moved 32 thou. 10 clicks on the rifle sight moved 76 thou.
With sight radius 'book' values of 28.6" for rifle and 23.25" for carbine that gives the rifle sight moving 0.98" per click at 100yds and the carbine one moving 0.71".
Fitting the carbine sight to the rifle would give 0.575" per click at 100yds. (anybody want to check the mathematics here?)
Ideally one would want to repeat this test with several examples of each.
Yes, it is one minute, for all practical purposes
