Airfoil was NN-21, work I have done in finding a NACA equivalent is based on data for NN series from Ki-27 maru book. Whilst not definitive it is the best I have been able to achieve given the few clues in text.
Root was 16.5%, tip 8% NN-21.
GoG / MAC location unknown at this time.
Estimated shape is:-
NN-21 16.5%
