Help me - I'm snookered!

Can you tell me where and who?

Searching through some old papers  recently I found this photograph of my father, Harry Brown,  (second from right) presenting a snooker trophy, probably taken towards the end of the Nineteen  Fifties.  Dad was a sports journalist, (though he mostly wrote about football,) and worked on the Leicester Mercury around this time. I'd love to know what the trophy was for, and the names of the others in the photo. 

Curious - me? My nickname's Alice in Wonderland...
