I have a number of this maker marked items which also has a triangle lozenge next to it with some other design inside it but cannot tell what it is. I have also seen many SP&S stated Antique or Vintage jewelry , mainly gold plate or gold fill chains ...

Have spent many hours without success on identifying these marks.If some one could enlighten me it would be greatly appreciated. The initials are clearly J.B. & has 4 x marks on the non lever opening side.
