The original documentation does not mention the name of the carter and it is not clear where the information came from, it first appears in the Ettlinger account, she thanks the then curator of the Museum, Tom Penniman, for information so he may have given her the reference, it is irritating that it was not recorded where it was obtained, as that source might have more information about the artefact.
