Hi,
I've inherited these photos of the Royal Horse Artillery F-Sphinx battery in (then) India 1938, together with one of the 4th Light Battery RA c. 1935, Bombardier Boyd being my wifes grandfather, and since the group photos are clearly named I thought they may be of wider interest. There's 4 photos with around 70 people, though there's some duplication (53 distinct individuals in all). If anyone spots a relative, PM me and I'll work out how to get bigger images to you.
Here's the first two . . .
