malabar coconut hookah from koyilandy,LOTS OF SILVER! unfinished stem

 I recently aquired what seems to be a very old hookah from Koyilandi..it is extremely tarnished i started to clean it but then relized it might be better not too yet.it has fish around the bottome base some silver and some appear to be bronzed of some sort and the coconut shell area has peacocks and flowers..and what is really puzzling is the long stem that is usually all wood.on this one is completly covered in silver and has started to be intricitly carved,but unfortunatly for what ever reason it was not finished. the only markings i can find is where the base unscrews from the main part on each side there is a VII ..you can see where i started to clean the base ..but relized  how truly esxuisite this piece is that i probly should not & stopped..it is built around a coconut.what you see in the pics is all that i have there is no bowl or trays or hose unfortunatly.but seeing as it was not finished im not sure if those items were ever even with this piece

i am trying to find out how old this is? an estimated value?who and where it was made?anything about the long stem covered in silver but not finished ..
