Yates - Eagle Symbol - WAR ... Need help here.

Today I bought a few old spoons at a local, out-of-the-way antique shop.

Two of them are large and monogrammed. On the back of one I can make out the following information:

The Word “Yates” / A Lyon Symbol / The Word “War”

I have loaded the photo into Photoshop and tried to filter it so the markings are the most clear.
