It is a staunton set.
It has some resemblances with Jacques of Staunton Designs from 1849, 1853 or "Paulsen" models.
It is very resistant and playable. Some variations of these sets have been used in some side events of tournaments. As the Gibraltar Tradewise tournament for challengers and amateurs.
