Shipmate , this one's a challenge but, looking through the old spy-glass the cap badge on the 'Old Man' seems to be a white cross on a dark background flag , but, not that dark to be black. Also, seems to have bars on his shoulders which most unusual and distinctive. also, plenty of life-boats and wondering if she some sort of pleasure steamer or ferry? 'Whalebone Corsets' , they certainly knew how to suffer properly in those days
Thanks for your info, It is annoying when there is no info on the back of photo, whats more annoying is that there must of been something on the back at one time, but this photo is a cut down post card, of course the bit with the info on the back is missing.
Interesting photo, man on left appears to be wearing a dog collar.
None appear to be dressed in a wealthy fashion so probably termed middle class and civilian dressed men all wear single-breasted jackets and a mix of shirt collar types, pre 1920s.
