I am looking for some information on this teapot, creamer and sugar. I have searched every Meridan and silver plate website I can find including the Meridan catalog from 1873. I can not find this set anywhere. The marking on the bottom is Meridan B.Company in a circle with scales. 1873 is underneath. I have attached a picture of the set. I would really appreciate any help anyone could give me. Thanks so much.
