Nearly 100 years ago - NOT amateur radio

This photo is nearly 100 years old. My uncle is in the front row in the middle. I think he was the foreman. It shows the Salcombe Council gang (Devon) in the 1930s I think. Love the moustache front left!

UPDATE 1251z:  Someone thinks this could be shortly after WW2.  My uncle certainly looks young though!! He was born in 1908ish, so the 1930s seems more likely to me. Mind you, the late 1940s would make him early 40s, so if he was the foreman, this would make sense.
