Kanazawa speaker. Who has any experience with these?

I have found a large cabinet set of these on FB for $100. My first thought was "can't be anything special"
The gentleman does not have a model number and all I can tell by photos is that they appear to be quite clean. A quick Google search yielded very little. Less than anything I have ever searched for. 
One of only two conversations mentioned Coral speakers, birch cabinets witch brass screws hidden with putty and fancy badging. These appear to match all those descriptions. 
Always being curious about odd ball/unknown companies and systems these have my interest. 
Can anyone be of any help with information on these?
