Not the actual weapon its self. However Gerald Bull was contracted by Iraq is build several superguns using technology and information gathered from his HARP work. One 350mm prototype was built. However the 1000mm full sized versions where never completed, the British stopped the export of the last pieces. However its unlikely they ever could have been completed as Bull was assassinated on 22 March 1990.
All the parts and the prototype where destroyed by the UN after the Gulf war, the invasion of Kuwait happened just four months after Bull's death. The main suspect is Israel, but not because of the guns, Bull was also doing work on Iraq's ballistic missile.
Bull also designed the G5 155mm artillery peice for South Africa. Most of the worlds artillery today is based off of this gun.
