What's up with Australia and Blue Wonders?? Seems like most of them ended up there (very unfortunately for me). Anyways, as vvti said, that's a great razor in great shape. Blue Wonders are really top tier razors, I don't think anyone would argue that. That said, and the fact that it's a family heirloom, I really recommend you get it professionally honed. Learning how to hone is a long process of trial and error, and you really don't want to be doing that with this razor. That'd be like learning how to drive in a Lamborghini.
Lots of guys from this forum live down under, check the classifieds or post a request in the Honing section.
