Just looking around the web - it looks like they never "got it going again" after they shut down a few years back... e.g. their corporate website is "kinda gone" - been hijacked by someone else, etc.
Your post did give me a bit of nostalgia - there was a young woman I went to junior high school with - mid 1970s - she had an ossa phantom (might have been her dad's but she rode it - lucky girl). The ossa was very fast and very beautiful - when new... I think it had fiberglass fenders - which didn't hold up well...
