Several people reported relatives owning Army Indian motorbikes that had been stolen from their properties or deliberately dumped. All these instances took place after the war.
"One person, for example, said that a farmworker he knew rode his Indian home cross-country every day after finishing work. When it eventually broke down, and became uneconomic to fix, the bike was unceremoniously dumped in a swamp," Edwards said.
"The swamp was located near Portland, south of Whangarei, however, and doesn't tally with the story of the motorcycle that we understand was found in a swamp near Kerikeri."
Another person reported the death of a man riding an Indian near Kaikohe in the 1950s. He said police disposed of the motorcycle by discarding it in a swamp.
"One person who contacted us told us a story that actually occurred during the war, the only such incident so far. It involved a soldier, who was riding an Indian motorcycle, tragically running into a wire fence resulting in some horrendous injuries that killed him instantly," he said. "The story is that this motorcycle also ended up in a swamp, dumped there by his comrades."
Heritage New Zealand volunteer researcher Jack Kemp first heard about the Indian from members of the Vintage Car Club in Whangarei, which cares for the battered bike.
Edwards said: "There are definitely some strong leads to follow up."
