Hi Torq145,
I think the trophy might be an early version of the Birmingham Senior Cup, (though I might be wrong) As your Grandfather was born in 1883, I assume this photo was taken just before the 1st World War? This would put your Grandfather in his early 20s. A place to start would be with two winners at that time, Aston Villa winners 1911-12 & Birmingham City winners 1914-15.
Hope this helps,
All the best
Alfie
