I googled a bit and found this old forum post
link.
The video examples are unavailable and I can't find the user on youtube.
The download link is dead and only leads to spam sites.
Seeing as this is an old voicebank and the condition of the links, it fair to assume they've might have left the utau comunity. The only way to get the voicebank would be to contact any who had him back then that are still active. Though bear in mind this is kinda in a morally gray area as it is uncertain if the creator of the voicebank would permit redisrtibution of the voicebank in any way.
