Dating Chantilly flatware

[claynfilm]

How do I date Gorham Chantilly sterling flatware? The marks are the style of the late 19th century but my grandparents acquired this in 1919 (married). I can attach a picture later but there is a sideways A in a circle centered on the upper portion of the neck.
