Reventlov, I think you have made some very good points. These bronze pommel variants of Wheeler VI do indeed resemble the sword presently under consideration.
They vary a bit from my expectations for Petersen type L hilts, as those that I have knowingly encountered have relied on rivets from the upper guard to attach the (often lost) pommel.
As the British Museum kindly allows distribution of the images in their
Portable Antiquities Scheme under a
