Undercarriage leg help

For those who don’t know, the Lockheed in question is the maker (or an offshoot from) of Lockheed hydraulic brakes, as found on many UK cars of the period.
The brake company was established by Malcolm, a brother of Allan.
The brake firm (or at least the American operations) was eventually sold to Bendix, who did a lot of aviation work during and after the war.

Further to the above, i am now the owner of the oleo leg. It came directly from the owner who was part of the team that recovered it along with other items and to make it that much better, it comes with a magazine article about the recovery and identifies the aircraft as L6960 PS-M from 264 Squadron which was shot down on 13.5.40. I just have to translate the article from Dutch into English.
As a point of interest, it does mention in my Defiant manual about the leg being manufactured by Lockheed.

Thanks a lot for letting me know, much appreciated.

Okay – i’m back and don’t have to type posts on an iPhone. Looks like Defiant to me. Mr Splits – if you send a picture to the RAFM i’m sure they will confirm. I never heard of Lockheed hydraulics as a British company making hydraulics during WW2. The company that made this leg and many similar items was called Automotive Products. They do bear the Lockheed logo though. They also made a lot of hydraulics for the Whitley and various other British aircraft inc Oxford, Magister, Skua, Mosquito and Battle. The company is still manufacturing today and have helped me a lot.

That would explain it then, thank you.

Lockheed hydraulics were a British company, and totally different to Lockheed in the USA.

There is nothing in the box to the left of the serial number but having checked my Defiant manual it states that the undercarriage is made by Lockheed which is very positive. There is only a drawing of the tail wheel oleo leg which isn’t wonderfully helpful.

I only have the photos that I have posted at the moment but I can contact the seller for more information.

It has been offered to me as a Defiant leg but I was sceptical as soon as I saw the Lockheed label but I thought that stranger things have happened and I would seek the advice of more knowledgeable people on here. I will check my Defiant manual when I get home and see if that sheds any light on it as well. Thanks for all the help so far.
Still kicking myself for not taking loads more pictures at Hendon’s open cockpit evening. Since going to that I have picked up a Defiant main undercarriage leg but I was able to identify that from my Defiant manual.
It would be great if it is Defiant because I am mad on the type and have picked up a few other Defiant bits recently.

British licensed manufacture of an American patent.

I reckon maybe a Miles, maybe even an early Miles type.

AP Ltd (later APPH ltd) started making this type for Miles but then produced similar for others.

Taking into account what Whitley Project said, Defiant is the best match I can come up with.

Your second picture even has traces of black on the upper portion!

Doesn’t look quite right for P-51 – the outer surface of the curved portion is too flat, and the whole section seems to thick/solid. Compare http://data3.primeportal.net/hangar/domeric_barbot/p-51d/images/p-51d_16_of_51.jpg
Not sure what it is though! Is the “Lockheed” makers plate a clue, or did they make undercarriage legs for other manufacturers?

This is off a British aircraft. The leg was made by AP. I’m in th USA right now but can check for you when I get back.

Is the box to the left of SERIAL NUMBER for the Type No? And if so, does it have anything in it?

I’m certainly no expert but they have a look of a P-51 leg!
