Please note email address is mr.david.beales@gmail.com. The phone number given by John-B was disconnected years ago.
We do not give out our telephone contact I'm afraid (as 99% of our business is now conducted via our Ebay shop) thus allowing me to concentrate on the actual manufacture of parts and reconditioning of units.
Ebay shop; google search "daimler classic car parts ebay" with over 600 items. You can also message through this.

Hi David
Thanks for this, I’m trying to source some valve stem oil seals for my 1951 consort if you have any?

Hi, yes it looks very much like a “Bray” water heater, same that was fitted to my Lanchester when I first acquired it some 41 yrs ago.
Have never refitted it ,and it’s “ lurking” somewhere with the rest of my spare parts .
Cheers Al
