Debodun, you might want to send inquiries to the Museum of Natural History (they do have exhibits of local furniture and products) as well as the Maritime Museum of the Atlantic, which specializes in the close ties with the sea and the navy. One of these may be able to help with dating the jug.......at least with finding dates for the existence of Scott's Army & Navy, possibly any roll he played in supplying ships, etc. with the 'good stuff'.
Actually you could cover all bases or be directed the the exact one to contact buy messaging the Nova Scotia Museum, which is the 'parent' of the 27 museums in the province.
