An interesting desk calendar made from an Egyptian round, not sure of the calibre, mounted on to a plinth with a plague stating 'Egypt 1956'. By unscrewing the base plate the date of the month can be changed by turning the respective shell parts clockwise or anti-clockwise, really interesting military ornament, came from an ex-Sea Harrier pilot. Length just over 10 inches, round diameter is approx 44mm, quite heavy too.
