With thanks to Yvonne Scott:
This photo is of Henry Wyse receiving the keys to the New Ambulance from Mrs Davenport who was the President of the Ambulance Ladies Auxiliary who raised the money to buy it.
As far as year/decade, I’m guessing 1950s but if anyone could clarify, that would be great.
Is this the same Don Burt who owned the menswear shop in Wynyard Street?
