Where to find parts for 1960-1970 spinning wheel from NZ?

I bought a spinning wheel from a yard sale and didn't know a thing a bout it. I did some research and I believe it to be a Sleeping Beauty spinning wheel made by Alex Baillie from NZ in the 60 or 70s. I think it is missing a Flyer Whorl and don't know where to get one for this wheel. I don't know if it even has this part because I know very little about this wheel. Would Ashford supply these parts? Anny info on this wheel or websites I could get info would be great. This is a pic http://www.nzspinningwheels.info/sleepingbeautymaddy.jpg. Thanks so much!!!
