I find it difficult to date as I have a similar photo of my father and his brothers in 1920s 
I'm not sure either Gadget, menswear didn't alter all that much and if it was 1920s I would expect to see a collar bar but not necessarily.
We need the poster to tell us which one was their Grandad and when he was born.
