to the best of my knowledge, no - neither the Mark Hill book or the larger Smithson's volume include any lamp surrounds such as this. There's a couple of hurricane lamp chimneys and a candle lamp, none of which is anything like yours, and then there's the legendary Lucifer oil lamp, but again very far removed from yours. Another feature showing on this one, is the noticeable shoulder bevel, which doesn't seem to occur on Dartington pieces.
Having waffled thus far, it's nonetheless quite striking how the central circular stylized raised sun motif - within the circle of dots - is very similar to an almost identical moulded sun motif that was used by Dartington. Let's hope yours wasn't a prototype lamp of immense value

Perhaps a bit of plagiarism going on here.
