This is from a post card dated 04.08.21 and shows the Howdon to Jarrow ferry at Howdon with Palmers in the background.
The ferry is, i think, the G.H. Dexter, it fits the date the card was posted.
The G.H. Dexter took the place of the C.M. Palmer that sank in 1916.
The ferry A.B. Gowan replaced the Dexter in 1921 and it is not the Gowan in the photo.
