Conclusions:

High End: I know it was 7 weeks ago, but setting high end at 12.5 for the sale of 13.5 in unusuals. 2 unmet B/O's of 13, so that shouldn't be in the range.

Low End: Highest offers of 11-11.5 in unusuals / rare vintages in the last month+. All rejected. So setting 10.5 pure as a generous low end.
