Where can i get a new case for my grandfather clock?

Its old case is already crumbling apart after the flood. case circa 1970-1980, dont know what time was it made. one time when i cleaned the outside of the case, a piece of the case fell out. and the feet doesnt look good anymore since it was flooded on the foot of the case. what i used is a piece of a wood to balance it. i live in the Philippines and where do i get a new case of it and how much?
