But the way I interpreted the original post is that the Chipmunk in question may not be Canadian. 12jag has just found a link to a windscreen provider for the Canandian hood.
Can we ascertain the type of Chipmunk and whether it is for a flyable model so needs paperwork for the part?
So does this mean P-38 wartime rads only lasted 10 hours, or are they using a different more available part? I imagine 10 hours TBR when in Europe would also be pretty limiting regardless of how GG got here
