The one photographed above is an atlas, an English is front loading.
Maybe you intended to upload the pic of the Atlas.
Seriously? Lol, I bought it on the understanding that it was an English! If only I knew what I was on about lol. On the plus side, I paid £120 for it so that must be an absolute bargain!
Yep that's 100% an Atlas axle! do you know what ratio it is?
English - the main casing is formed steel not cast, just the pigs head is Cast. and the bolts are too the front (front loading)

If you want to identify exactly what you've got this might help - What Is The Difference....Atlas & Baby Atlas?
Yeah that's not an English axle, the diff in an English axle is bolted on to the front. It could be any number of atlas axles or it could be a Koln, if it's a koln then you'll struggle to find an LSD for it. If you put up a picture of the diff mounting side then it'll be easier to identify.

sounds like you were told a lot of things! refund?
Its a 52" full Width Atlas axle, the drain plug gives it away & diff cover is rounded.
To Check ratio - You can see how much one rotation on the input rotates the wheel flange, or you can pull the diff down and divide the Crown wheel teeth by the Pinion tooth number.
On Sierra diffs there are some stampings on the casings to tell but at this stage who's to say it hasn't been altered. 3.75:1 is a popular ratio and was installed in lots of models.
Are you staying on rear drums? if your going discs you will need to have the hubs lathed down or the discs opened up by a few MM.
There is very little need for the rear braking.
The only major advantage on a 7 would be getting rid of the weight of the drums, cylinders & shoes for a nice alloy calliper and lightweight disc.
Are the conversations not pretty expensive though? I'll probably go that way but will stick with the drums on the rear for now.
Not if you go with the handbrake Sierra Calipers,
I actually have a pair of Weld on mounts for sierra calipers on atlas axle and Lightweight discs to suit in the garage if you are interested!
Would take £75 for the Discs and Mounts
