WMaker... Just for <G>'s which version of the Mohawk are you espousing, Keeping in mind that the later two never made it to France, 1 which could out turn and out fight the Ki-43, or the 900hp A-1... transparent? Also what are your thoughts on the Prototype Model 75B related to the B-239?
Thank you,
