Update on XK120 ENV axle numbers

I thought I’d post the current version of the ENV serial numbers list that I’ve been compiling. It seems likely that that the JHS number was stamped by Jaguar during assembly of the car. Those numbers very nearly follow each other chronologically. I think the "No.- - - - * must have been stamped by ENV, I think. The vast majority of the axle details I’ve so far collected show the standard ratio of 14 51 - 3.64:1.
Of course, I’m only too happy to add more numbers to the list if anyone should wish to oblige. A photo is great, too!

Hi Chris –

You can add this one to your list as well:

JHS 322
No 2611
14 51

This resides in my March, 1950 steel OTS car 670236. Ratio per the numbers is 3.64. I had it out recently for a good clean up as part of a generalized rebuild of the brakes. The numbers weren’t very legible so I sprayed some white paint over them then quickly wiped the over spray off with a rag dipped in spirits so the marks would stand out.

Hope this helps.

Thanks very much, Christopher. Great to have another one!


Stamper had a lazy day. Best I can make out:

No. 4388, JHS1555, 14-51, 660365, Steel, 28/11/50


That’s brilliant, Matthew. Your numbers seem to fit the pattern perfectly!

Here is another data point that seems to fit.
Steel OTS
build date May 11, 1951
numbers on diff:
NO 4609
JHS 1672
14 51

Many thanks, Jim - it fits right in there!

I’ve been watching this thread since it was started, I finally had a chance to get my numbers for you.

NO. 3481
JHS 921
14 51

numbers seem to fit right in the list

And the green paint, too.

Thanks a lot, Cliff. Fits the pattern perfectly, so no surprises there.

Yes, mine’s green too.
