@prrhorseshoecurve posted:Williams did make an F7 B unit for their ex Kusan F7s. They sold them separately from the AA sets. What are you talking about?
I never said Williams didn't make F7 B units as I'm the guy who answered his question on what the B unit in the video was. Not sure what you are talking about.
I have no idea if AMT or Kusan or anyone else that originally controlled the tooling ever produced a B unit nor do I even care.
