A new old stock Laycock de Normanville 65579 or BMC number 17H5865 overdrive planet carrier assembly that is very likely the last remaining NOS part in existence.  The photos show this rare part still encased in the old cosmoline and protective paper being opened up for these photos. This BMC boxed 17H5865 part fits later model Austin Healey 3000 overdrives. This part is for someone wanting to build a want to be perfect overdrive. In the original Laycock box with a BMC label. I cannot say for sure but this part may fit some Jaguar overdrives as well. We do not have a Laycock parts book to research other applications.  The Laycock part number is 65579. Do your research if a Jaguar application. Perfect condition, a planet gear carrier assembly still in the original box with protective paper. A piece of Laycock history as it is now made of unobtanium.

We have an inventory of new old stock parts from British car dealers that retired and import parts houses that closed. Many NOS parts have been stored away for decades and are now coming to the surface. Parts data was kept on paper key card files by hand as computers did not exist so listing and identifying parts now is a laborious process. We have made a lot of car owners very happy with rare and basically unavailable NOS parts we have been able to provide.

Some of the parts are ours and others have been donated by our automotive clients that are aware of our animal rescue efforts. Preparing and selling the parts is essentially a free service we provide car part donors. They get the parts out of their life without a hassle and enjoy knowing where the proceeds go.
