Identify my rear end?

[Lowtus7]

Hello, I was looking to the community to verify the differential on my Super7 kit car.

I'm pretty sure its just a standard English axle, however,  I was unable to find any pictures etc on the net of exactly the same casing. And wondered if anyone could tell me the exact model this diff would have come from. Its a 4.1 ratio. Any help would be greatly appreciated.

 

Kind regards

As English axles have been used on many Ford Models from the 50's through to the 80's it would be hard to identify exactly - Popular's, Anglia's, Escort's and Cortina's etc. But that diff ratio 1: 4.125 is usually reserved for lower powered variants ie. 1100cc or 1300cc as they didn't have the torque to pull higher ratio's!

Yeah English axle,would be a earlier one as small flange to prop shaft,the width of the axle (case, flange to flange)may identify which Ford it likely come from,these made in many widths

Thanks guys for your replies, I guess I was hoping someone would recognize those markings. Other pics I have seen online don't seem to have the "S" and the "5" like mine does, and often have markings closer to the input shaft. I figured it may be a "bit of an unusual one", and wanted to check before I made any decisions on maybe changing ratios, and/or getting a LSD center for it. I think there may be some other markings a bit further towards the bottom, its just hard to make them out with the diff in the car, and the glossy finish of the paint.

 

Thanks for your input!
