Information on Westinghouse China?

My grandmother gave me her antique china set before she passed away. I am having a hard time trying to find any like it. It is an entire set with every piece included. It has the dinner plates, cups, saucers, bowels, gravy dish, etc. It comes in zippered cloth cases. The dishes are white with a silver lining. Unfortunately, all it says on the bottom is "Westinghouse." I know she had them for at least 50 years.

As I do research online searching for Westinghouse china dinnerware, all I can find is information that the Hall China company made some dinnerware/china for Westinghouse, but the images I find are nothing like the set I have. I am just trying to find out any additional information about this particular set. I am in no way interested in getting rid of it. It would just be nice to know what the value of it is. If anyone has anymore information on it, that would be so fantastic. As I stated above, it is a very simple, yet pretty set with white dishes with silver lining, says Westinghouse on the back of everything, comes in green cloth zipper cases.

Thanks.
