A retired engineer facing a series of firearms charges has an addiction to making and test-firing guns, a court has heard.
David Cunningham discharged home-made weapons inside his east Belfast home and out at sea as part of a fascination with their construction and operation, a judge was told.
The 63-year-old was remanded into custody on eight charges, including possession of handguns, zip guns and Taser stun guns. He is also accused of having gunpowder in suspicious circumstances, possession of ammunition and discharging a firearm in public.
Cunningham was arrested after police searched his house at Castlereagh Parade on Monday.
Officers seized nine zip guns and handguns, four stun guns and a large quantity of bullets and shotgun cartridges.
Defence solicitor Adrian Harvey told Belfast Magistrates Court that his client gained his knowledge during a 10-year engineering career. Material was either bought or retrieved from skips, the court heard.
Cunningham will appear again by video-link on June 10.
