How many tennis courts has Tonbridge lost?

Recently Tonbridge Daily posted the snippet that in 1923 the Sportsground had the enormous number of 57 tennis courts. Many of you contacted me in disbelief that Tonbridge had so many. I think you were doubting me.  I have since found this map of 1923 in a town guide that marks the tennis courts, and I may be mistaken but I think the number has risen even higher to 61.  Take a look!!!!
