The 22p value of the Jersey stamp issued depict the paddlesteamer LONDON according the Stanley Gibbons; Collect Ships on Stamps.
In Log Book Mr. Hogan has a paddlesteamer LONDON built in 1853, the Enzyklopädie der Maritimen Philatelie (Navicula), gives first that she is a coastal paddlesteamer by entering Naples, but gives than the details of the screw steamer London built in 1856 by Gourlay Bros (not Gowlay).
The title of the painting is; Paddlesteamer entering Naples.
I believe Mr. Hogan is right, that she is the paddlesteamer built in 1853, there was a other paddlesteamer LONDON built in 1837, but she never was used from Jersey, and she was later sold to Australia.
I believe the LONDON never has been to Naples, but it is more a fantasy background painted by the painter.
