The final day of filming for Heritage Rescue season 2 just wrapped. The Top-Shelf Productions show started shooting the 8 episodes back in February. Today was a pick-up shoot to most notably film the firing of the 132 year old 'disappearing' gun (1885) on North Head, Devonport, Auckland NZ. It has only been fired a handful of times in the last century. It's first firing was in 1887, 2 years after it was built, to test if it actually worked!
