I have recently acquired a very rusty wilkinson sword Sn.14015. It has markings for the "Royal 2nd Middlesex militia", VR, and what I understand to be the usual wilkinson markings for this era. It also has "nullius in verba" and a two letter scroll of what I think is AE. I believe that this is the motto of the Royal society, Possibly the aeronautical socitety? Can anyone tell me if this is unusual, or suggest a reason for the inscription?
