cary london fusee clock

[rrdd123]

I recently purchased a Brass clock that is signed to the dial CARY LONDON. I have tried to research this clock and have only found CARY as scientific instrument makers in the 18th & 19th century although I do believe they may have made chronometers.
 
So I thought I would pick the brains of the best.
 
The clock is heavy brass weighing 7.5kg 11" x 7.5" x 4.5"
 
It has a platform escapement and a fusee movement.
 
I have enclosed a couple of photos and would appreciate your opinion on it
