Here's the 1934 built Volunteer, predecessor to the John King. Like the John King she was built by Charles Hill & Sons Ltd for CJ King & Sons Ltd. She spent much of her working life towing ships up and down the Rover Avon and within Bristol City Docks. When built I understand her to have been the first diesel ship handling tug in the Bristol Channel.
She to moved to F.A. Ashmead & Son where she was renamed Robert A. She later left the Bristol Channel area for Wisbech where she worked into the 1990's before entering lay up. Sold to a private buyer she was partially restored before heading to the North West of the UK again in private ownership.
