The 2 players at the left in the top row both appear to be wearing hooped caps. The cap combination jersey for the player 2nd from left appears to match that of Erve Beck in the individual image.

Observing the individual images of George Yeager and Ollie Pickering they are both wearing the same combination of dark cap, dark jersey and light trousers. This combination would match the players in position 3 of the back row and position 1 of the bottom row. Comparison of Genins and Pickering with the player in the top row attached.
