I think you'll find the P-51's more handsome and slightly older (and IMHO better looking) "uncle" from overseas, the Supermarine Spitfire, did it first - and then allowed the P-51 to "borrow" its engine as nothing suitable was available at home. *

*(I should acknowledge of course that the Merlins used in the Spitfire were pretty much "hand built" due to the design which was very inefficient for production. The P-51 version of the Merlin (redesigned in the US during WW2) was transformed into a mass produced engine, and improved along the way. Created by geniuses, improved by very smart engineers.)
