It's kinda a long story but I'll keep it short.
The Fellow has an old 1946 Humber that he's trying to restore- but it has a different engine in it. Something went wrong with the water pump and he can't get replacement parts because he doesn't know what kind of engine it is... Maybe an old Husky or Minx? a weensy little side-valve.
Sorry to post something so off-topic and RANDOMZ but I've been scouring the internet for any kind of info with no luck. I've tried to join a forum specifically for really old-timey Rootes Group products but still waiting on it and the fellow is getting IMPATIENT!
The water pump is supposed to live on top of the motor and the radiator has been altered to suit.
Anyways, here's the photos:
