Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
This is a brass centerpiece bowl (nothing to do with christening), and would have formed a three-piece garniture along with the candlesticks. Can you post a photo of them as well? And a photo of the underside of the bowl?
Any marks, stamps, or labels anywhere on any of the pieces, even letters or symbols or numbers?
Understood! No worries! Any photos of the candlesticks?
