TC asked if we'd confirmation of this ID, and the answer is yes. It's in Angela Bowey's Bagley Glass (3rd edition, page 58) and was included after Angela attended an event with ex-Bagley workers where she discussed it with them, and where several workers confirmed it as being made by Bagley, probably carrying the no. 3003, to match the Bagley butterfly lamp. Pontefract Museum have had a set listed as Bagley for a while, which is what prompted the discussion.
