Three studies of fighting vessels firing guns, possibly including HMS 'Devastation' and 'Thunderer'<br>
The top two sketches are probably intended to depict the turret ships 'Devastation' (1871) and 'Thunderer(1872) during exercises in the 1880s.  The bottom sketch is  clearly a similar subject but not identifiable.
