VTG Blackinton Gullloche 4 Set Salt & Pepper Shakers in Original Box

These are Blackinton silver plated Guilloche salt and pepper shakers. Two have worn silver plate on inside and outside of their lids. Guilloche has some wear, and I found a tiny piece of glass, but can’t find where it is from. Four shakers in the original box, you can use with no worry for some nostalgia! The original box is a plus!
