Just couldn't resist a second go...
I'd put the date around 1905, year or so either way.
I think the waistcoat is quite ordinary for its time and the man wears a shirt under it. You need one of the clothes experts to be sure.
I've got a similar problem with one of my photos. My Mum, sadly no longer with us, stabbed a finger at the photo and said 'That's Eliza Ann.'
Her finger covered several little ladies in the group. I wish now I had asked 'WHICH?'
But at least I know my most troublesome ancestor is there....somewhere....
