Just been helping a P Type owner with his restoration. Found this in my file which may be of interest. Drawing and measurements of the battery tray I once had. Interested if anyone has a photo of one out of the car. Not many original ones left of these on cars I imagine. Donald McLeod PB0759
Just bought an "original Rare Part" per vendor on East Coast USA, Looks to be the exact one from your drawing never installed on the J. See what you think?
When I received it I can say it has never been fitted ever, Also is certainly not circa 1930's, but a re-pop. I sent the vendor a few words of my dissatisfaction with the misrepresentation....
