Yeah, Probably.
I know of at least one other in Perth - it's a one owner bike. The bloke bought it new in 76, raced it for a couple of years, then parked it in his shed.... Before I found my other bike, I tried for about 2 years to talk him into selling it.
He was restoring an IT175 at the time, and I think he was looking to put the money from the IT400C towards the 175. But when it came down to it, I think he'd had it for so long that he couldn't part with it....
