Not sure who this was for, its marked W C as an overpaint over an A for ambulance. I can only guess at WC, Water Company or Warden Command/control or what??? If anyone knows I'd be happy to be told.
Condition is not great but the shell is dated 1939 next to one of the lugs, the MKI liner is marked size 7 I VERO 1939.
It has a rusty crappy black paint and has a hole in the front, perhaps to attach a head torch or a badge.
It was local to me and was very cheap.
