Grigson had it registered N215RG as the Grigson RG-8 on June 9, 2009, two months later, August 11, the aircraft received an CofA. Remarkably, the aircraft had applied an RNZAF roundel on the starboard side and a RAAF roundel on the port side. Later Grigson moved to Strathfieldsaye, Victoria, Australia, and had his aircraft reregistered VH-NZG on March 5, 2013."
