Hi! Lovely set of china! Yes, they are worth something...but it depends on where you are located and demand for items like this.
Seems you have most of a luncheon set. (Tea cups, saucers, luncheon plates, cream/sugar) and a sauce boat would have been popular to use in the 30's to 40's for luncheon items.
Here is information about the W S George (William Shaw George) Pottery Company on the official site.
http://wsgeorge.jdfiles.org/The pattern of the set you have is "Derwood".
Unfortunately so many companies did not have computers back then and didn't have their patterns categorized/noted in books or on computer. (It was all about producing and selling.) Even on the official site or Replacements, LTD. this pattern isn't noted. You may want to add it to the WS George Co site so others will know the pattern exists.
