Limoges set of 3 serving dishes

I recently cleaned out some dishes that had belonged to my mother (and potentially her mother and grandmother).  There are three dishes that are different from the rest and I was curious what their value might be.  They appear to be a set of three serving dishes (two plates and a bowl) by Limoges from the early 1900's.  They are an ivory color with gold leaf around the rims.  There is a gold leaf design in the middle of each that reminds me of a wheel on a boat with a flower in the center.  The maker's mark on the back includes both the purplish bell and the green "T&V France" designs.  The Bell includes the words "decore par Limoges T.V. Pour Wm. Lairton WILMINGTON".  I have attached two photos I took of the set and the maker's mark.  I am trying to determine the approximate value of these dishes.  Additionally, I am from Wilmington, Delaware.  I was wondering if the "WILMINGTON" reference on the back is from Wilmington, DE or whether they were painted in a town in France.
