Webster

9 5/8 inches and 1 1/8 inch deep, 251.7 grams, 8 troy ounces.

Marked with the Webster WC with an arrow and "Sterling 24715."  Made in Massachusetts 1894-1950.  Webster often custom made pieces for wealthy customers, so this piece may not have matching pieces.

Condition:  Very nice.  It has a very slight dent, or bump at about 4 o'clock out from  the monogram.  I think you can see it in the last picture.
