Unknown Reed and Barton pattern

HI I am new to the forum. I will post a picture of this piece later. I just bought it today. It is a very large Reed and Barton silver plate platter/tray with a 1938 hallmark and is marked 1400. It looks like a water lilly leaf and has two flowers on either side of the handle. I have been looking at Reed and Barton sites for hours and cannot find the pattern or the value. Can anyone give me any help with this?
Thanks so much,
