From the information available it's basically an LS85Q with some cosmetic changes so that would be a good starting point in terms of value. It's certainly rare but not well known or highly sought after, and the condition is going to have an impact on value as well.
All that being said I still believe you got a fantastic bargain. At the end of the day it's still a quilt top MIJ Tokai. It shouldn't take much to restore it to its former glory, just don't expect to retire off the profits :lol:
