This is a picture of Vehicle Ferryboat No. 4 outside A & J Inglis Ltd in Glasgow. I've not had much luck finding out any other information about this so comments welcome.
**Update** I've since discovered that this was built by Ferguson Brothers in Port Glasgow in 1938 for the Clyde Navigation Trust. It was used on the route between Govan and Partick. More information here.
