Why, GPMG?
Because doing something nice for the IAF seems to be a good thing to do. They have done a great deal for 'King and Empire' in the past, after all.
I don't support giving P7350 or LF363 away, however, so buying the NZ Hurricane for the purpose would seem to be a 'good deal'.
Perhaps the IAF could also chip in a Canberra B(I)8 to replace the one we gave away to New Zealand?
