Many thanks for the replies.
I'm fairly convinced now that Jack Duthoit is the fourth person from the left at the back, Tommy Louden is the third person from the right on the back and next to him is trainer W.Toynton. Alex Bloxham is in the front row on the left. If Freddie Kurz is in there he may be the player between the keeper and Tommy Louden.
So given womble's response which has those players listed in it, it looks like it could be a photo of a team from the 1952/3 season. But what is Ray Middleton doing there?! He didn't come to Boston until 1954. The Chesterfield historian reckons the player holding the ball looks like John Evans who joined us from Chesterfield in 1957 when Ray Middleton was manager.
So there are still a few loose ends need sorting out. Any suggestions?! Perhaps a team put together for a testimonial for someone in 1957 made up mainly of Boston players from 1952/3.
