Silver Condiment Serving Set

Is the mark clear? I cant find any info on Rider B. but there is a company named Meriden B.Co.(Meriden Britannia Co. of Meriden, Connecticut). "The "Meriden Brittannia Company" was organized in 1852, by more than a few independent manufacturers in the area of Meriden Connecticut. Their purpose was to produce quality and quantity in brittania (a silver-white alloy close to pewter) and plated silver holloware. You can read more about Meriden and it's manufacturers in the Encyclopedia of American Silver Manufacturers 4th Ed., by Rainwater and Judy Redfield 1998. The "Meriden B. Company" became incorporated into the International Silver Company in 1898, but still used it's various company marks into the 1930's." Your condiment stand probably dates somewhere between the 1880's through the turn of the century. They were most popular at that time. Is there a scale in the mark? If so then its Meriden. Does it say it is silver? It should be marked if it is sterling and has a huge impact on value. Can you get a picture of the marks on the bottom? Thanks
