I was asked by a friend to help out an estate sale he was holding. He purchased the contents of his neighbor's home who passed away. A portion of the furnishing was a Berkey and Gay bedroom set. Part of the fun of the dealing in antiques and collectibles is the researching of new found treasures. I found the following website helpful to begin my research.
A few books on the matter helped out too.
We eventually settled for $1000, and sold the set to another neighbor.
