Sterling silver vanity set

I have a set consisting of hairbrush, handmirror, and comb.  The brush and mirror both have hallmarks on them of 'sterling' and what looks like the letters SLB in cursive.  The 'L' is smaller than the other two letters and is over a small shield of some sort.  The word sterling is to the right of the letter 'B'.  I am most curious about when the set was made, and by what company and any other information that can be provided.  

Good
