Rie-inspired footed bowl with incised decoration, mystery mark!

I am so intrigued by this piece that I am considering offering a reward for information! It is a well-made, confident bowl with incised decoration and a very clear maker's mark that I just cannot identify. This pot came from the estate sale of a very wealthy family in Ireland but it could be from anywhere






I would appreciate any information including random guesses! Thanks in advance!

Welcome to the forum. Unfortunately there is no comprehensive database of Irish marks yet, but I am working on it. I haven't come across this one yet but when I do I'll post the info.

Sorry I cannot help, but just wanted to say that it is a lovely piece. Never seen this mark before.
