Tiered Serving Tray with W-A stamped on it

Hey all! Helping a friend organize her massive warehouse storage space, and we found some old metal that shes had for ages. I have this piece, a tea-set, and two trays, and we have no idea where they’re from originally.

Here’s the serving tray with the marks. Any info is helpful!

It’s an electroplate mark of the Birmingham company William Adams Ltd.
