They do list one on their web site. Personally I would never ever buy from them again. Mine is a B1 model from 81. They listed a filter for it. Too small by a long way ! They stitched me up good and proper. I finally had to provide them with a drawing. They made one that fitted perfectly. They then sent me the other 3 that I had originally paid for. Different again. There was even one obvious piss take filter that was huge. Sorry, just my opinion.
I guess you would be ok if you're in Oz. For me in the UK it was a nightmare.
Saying that, the ones that fitted are damn good filters. Have a look at the web site.
