Dennis fire appliance in action, Grey Street Newcastle. Believed to be outside the Green Market. The pump operator is venting the pump via a delivery valve, to prevent overheating when operating against a closed branch. Lockers can be seen open in this shot - hinged top opening types. Also suction hose lockers (top rear), which were missing from earlier models. The thinking being that 'there was a hydrant on every corner' in a compact urban Brigade. Soon found to be false
Grey Street, Newcastle, mid 70's.
