While not marked “Mordan”, it is identical to “Travellers” made by Mordan at that time. A well known collector and writing equipment expert indicated that the Dowager Duchess of Athole likely had several of these custom made without the Mordan imprint purely to allow adequate space for the lengthy inscriptions that she was placing on them prior to giving them out as departing gifts when she left Athole. The imprint on this one – “John Robertson from the Duchess Dow’r. of Athole Dunkeld, May, 1864”. The combo includes pencil, pen, compass (in finial), and thermometer. This is a rare example as the thermometer is still intact (with its mercury).
