Welcome to the Forum Bobowler. You are right, we did say the Corporation more often in those days than we do now. If we said City Council in those days we would have been referring to the Councillors, something not too many people would have done. The buses were Birmingham Corporation Buses. Back in the 1920s, Birmingham Corporation ran everything, buses, police, fire, ambulances, gas, water, electricity, dust carts. We even had our own bank, the Municipal. Birmingham was virtually a city state.
