I need help with this Staunton

I bought this set in Brazil,  although I am not sure if it is originally from there. The King is 10 cm, Basis 4.6 cm. Quite heavy. 
 I appreciate any information you can provide regarding this set. For example,  how old it is. I couldn't find a similar set in my books or Internet. 

Thanks for your help.

Nice looking set , The rooks look very small for this size set ?

Yes, and the form of the rooks is also special (the top).

Still nobody who can say something about this set?

Look like a English set with some kind of grounded Rooks , As the rooks are way to small without the battlements , Or so the base of the rooks looks wrong for the size . A mixed set ?

This is going on posted photo etc so can be wrong ?
