I was just about to say the same thing. Nick, if you have trouble uploading a photo, send it to webmaster-at-bristolcars.info and I will upload it for you (in the antipodean morning).

I take it Brian doesn't have any? (which is a bit of a worry)

If it's the same as the 408-411 then it's similar to those used on the Astons, but unfortunately not quite the same (different mounting style). However, it will be the diaphragm that has perished and those valves do come apart, so in a worst case scenario you could buy one for a DB6 and use it's innards to renovate your valve.

This could be what you need Canley Classics - New Catalogue - BODY AND FITTINGS - Spitfire / GT6 Heater

I mean the valve!

If your 407 is similar to my 408 try Daimler or Rover.
If you put a hose clamp on the hose meantime it would save driving in
your swimwear!
Alternatively some BL cars fitted a manual valve on the head for
isolaton.

Thanks Kevin,

Tried that route but the 407/8 has two controls.
Brian does not have any and indeed does not have a clue as to which car they
came from.
I even spoke to Brian May but the state of the 407 he has just obtained for
spares is too far gone.
I will attempt to upload but will send to you I think as I am still a bit
clueless.

From a muggy 24.5C. But sunny.

I have a few photos (see below) of the valve on a 408 and a 411. It appears that on the 408 (green car) that there is only one cable. On the 411 that is certainly the case. So maybe the valve on the 407 was different from the later V8 cars.

Whatever you do don't undo the screws which hold the heater valve bracket to the heater box - the nuts behind are NOT retained!

Incidentally, I have just been through the parts list for the 408-410 and I can't find that valve!

From a brief look at the photo and my 1963 Alvis TD21, the valve on the
Bristol and the Alvis look to be the same, except the Alvis valve is on
the right side . It has the flange to body and same outlet.
I believe that Red Triangle at Kenilworth may have stock - I recall they
were advertising " repros" of one models heater valve a while back
