I recently came upon this silver candlestick holder and have been stumped by the mark on the bottom. I’m quite new to silver and could not find any information online about the mark. The holder has patterns of flowers along with individual flowers on the base. The inside seems to have white on it that is peeling off. I’m also not sure to what this is. Maybe paint of some kind? If anyone could help with identification, it would be very much appreciated!
Thank you!
