Good evening,
The portly gentleman is a Lt in the General Service Corps or is an officer on the general list. (officers with no regt). I say Lt but he could be a captain, i'm not sure when the rank insignia changed.

He's definatly a Lt, the rank insignia changed in the 1880s.
Ahh...No...Sorry...he is neither!

The GSC wasnt formed until WW2, and the general List would have brozed bades...He is in fact a member of the National Volunteer Corps .... The National Guard...A form of "Home Guard" formed in WW1
