Classic cars forum & vehicle restoration.

An elderly neighbour has asked me about a differential which has been lying in his garage for years. I wonder if anyone can identify what car it is from. I have sent details to the Standard Motor Company but as yet, have not had a reply.
His late father ran a motor engineer business from before the war until the’60s and the diff is a remnant of this.
As a car enthusiast I am keen that potentially rare parts are not lost.
The unit is large and, by its appearance I think it may date from the early ‘30s.
I have attached 3 pictures and the following information may also help.
It is approx. 10” in diameter and 16” front to rear.
There are 10 stud holes round the circumference.
A plate on it is stamped “Made by ENV”.
The following numbers / letters are stamped on the circumference:
26650 ENV No BD927 DF922
It is also stamped 9.42 which I guess will be the number of teeth in the pinion and crownwheel.
As you see in the picture it is clearly embossed with the name STANDARD and the number 33 is also stamped on it. This is possibly the year of manufacture.
The unit is in good condition and very clean. I speculate it may have been overhauled for a customer and then never collected.
Can anyone identify what model of standard this is from

I am sending you details in the hope you can identify what car it is from and if anyone in the club is looking for such a part.

I know my neighbour hopes to get some money for it but he will not be difficult to deal with if someone wants it.

Hi Ronnie,

I think you've got it fully suss'ed. These ENV axles are very easy to work on so even if not already restored it's a useful item.

Thanks for the replies but I am still hoping to get more specific information as to what car it is from.
In the meantime I have done a little research and into the ENV company. They were a respected engineering company who specialized in gear cutting and they made diffs and gearboxes for several "high end" cars. I wondered if the diff was generic and used by more than one car manufacturer with only the embossed name being changed.
I should have mentioned that the half shafts for this diff would have six splines.
Incidentally, at the time of writing I have had no response to my enquiry to the Standard Club.
