Sarah,
I have a boxing bill from 1949,Maurice would know some of those on it,but for some reason I am unable to post it.Also have you looked in the Astonbrook through Astonmanor site there are some photo's of U.T.S.on there,also my boxing bill.
Mohawk,the teachers on your photo's are, from the top left to right Mr.Hill and Mr.Tomlinson,then Mr.Gill,don't know the middle one and "killer" Cooper.then,Reg Milner and Mr.Tomlinson again.
