Thank you Archer, I thought my post may have been invisible. ; )

With regard to the MT blades made for the F-82 restorations, there are of course a couple of other limiting factors if one were to consider using these on other Mustang types – for one, that blade design was never in use on P-51A/B/C/D/K’s in original military operation, and thus a lot of owners would have trouble with seeing them mounted to their aircraft since it wouldn’t look period-correct – and second, these blades are made for use only with the Aeroproducts prop hub, not the Hamilton Standard prop hub. Not only would an Aeroproducts prop hub be required, but the nose cone/spinner is also of a different design and construction for mounting Hamilton Standard propeller hub/blades versus mounting Aeroproducts propeller hub/blades. Of course if there was such a dire need for Mustang propeller blades beyond current supply (which seems to be not an issue), it is wonderful that such an alternative option could be sought.

I had the opportunity to visit the Pat Harker F-82E restoration back in November 2015, and there was quite a bit of discussion over the development of these MT propellers and loads of testing required. Harker of course has all of the completed blades now for his aircraft (as does Reilly), but this prototype blade was shown to us as well, to demonstrate their construction. As I mentioned earlier, they are primarily made up of wood and resins, but then are covered in carbon fiber and painted. With this prototype blade, you can see it minus the carbon fiber/paint layers.
