Hi ,
Looks closer to 1780 to me (could be earlier or a little later, would have to be seen live to be sure) and very probably English,non lead metal was also used in England but more likely in this case its the shape that's limiting the ring ,try a gentle tap with a pencil on the edge of the foot , that should ring,it may well be non lead but doesn't look it to me.
cheers ,
Peter.
