Unusual vintage Chinese pewter (tin) sculpture

Hi! I found one interesting statue from fleamarkt and i dont have any idea how old is it? Where its made and who made this.Sculpture is made out of tin and later few times overpainted. There is no marks or signs. The sculpture is hollow. its not molded,plates of tin are welded together. Weight is about 2 kg.
Has anybody information about similar sculptures.

Thanks!
