I have attached a picture of the sterling "Kingson" this time. Being made for the British market in the 1950s or 1960s it is labelled "Empire made" and "Reg'd in Britain". I think it was made in Hong Kong and is a cheap copy of the Addiator Arithma in aluminium alloy, size 6.5" x 1.7". The stylus is metal. Britain doesn't have an empire any longer, except perhaps for Gibraltar and the Falkland Isles.
