All good Dave.for me there was not anything in the photo to identify the location.
I have many others in the collection similarly of locations of a craft a float not easily knowing where.

Built for Birkenhead Corporation in 1962 by the yard behind her in the photo (Cammell Laird) she was originally named Overchurch after a housing development in the town. Unlike her near sisters Mountwood and Woodchurch she was built with the full width wheelhouse rather than the traditional local design of small central wheelhouse and bridge wing cabs. She was originally powered by twin Crossley engines and had chain telegraphs installed. During a major rebuild in 1998/9 she was re-engined with Wartsila plant which was directly controlled from the wheelhouse. Before re-entering service she was renamed Royal Daffodil which had been a name used in the Wallasey ferry fleet (the two fleets were amalgamated as Merseytravel in 1968). Royal Daffodil was withdrawn from service in December 2012 and laid up. In April 2019 she was sold for further use as a static bar / restaurant / event venue in the Canning Dock. She was gutted internally and had her engines removed. She was due to open to the public in Summer 2020 but Covid-19 has delayed the opening.
