Theoretically ,12087A vs. 12149A will give just 3-4 km/h of advantage for the former at low altitude, and ~10 km/h for the latter at high altitude. In flight tests both gave equal speed down low.
Why MW50 "for sure"??

JC Mermet mail when the photo was in auction ... In October 2010. And correction, I'm sorry, GM-1 not MW50 ...
