Is anyone able to let me know if there's anything identifiable indicated by this uniform and cap badge? The photo is from an album of a man who served in the 21st and 22nd London Regiment (First Surrey Rifles) but this looks like some kind of naval officer uniform to me, so I'm assuming he may be an unknown friend or family member... The album is mainly 1915-1920 but has a few items circa 1920s-1931, so I'm assuming this photo is from the latter period, but anything would be useful to narrow things down.
Thanks so much.
Best wishes
Chris
