What does the inscription on my silver cup mean?

[mewtwo2]

I have a Derby S. Silver plated pitcher with the inscription "P.O.W. 1931 Mens Singles" does anyone know what type of tournament it could of come from? I thought tennis or golf but could not find any info in my research.

P.O.W. does not come up except for prisoner of war.

"Men's Singles" sounds like tennis.

P.O.W. could also mean "Prince of Wales" or it could be an acronym for a local tennis club. This looks like a trophy from a local tournament.

Does this have a maker's mark / stamp?
