This is a really cool write-up. Another thing that might be of interest was the performance of the aircraft. There's a guy in Texas with 6 non-flying 109s, a couple P-51s, and some other stuff for sale as a lot. He's a former stunt pilot, flew in the movie 'Battle of Britain' and several others. In his words, the 109 handled much better at the limit than the P-51. The P-51 could dive and go very fast, but with poor control. In his opinion the 109 was the superior aircraft. Not sure if it relates at all to the prop discussion, but maybe in the grand scheme of engineering? Those warbirds are fascinating pieces of hardware to me.
