Oh and
Let me S'plain,
Some may have noticed the aluminium outer shell sheets buckling from the steel frame movement over rough roads, Post#47, so Dad called Michican Arrow, ( and at the time we only had one cell phone among us ) and told them about it. So if you'll notice in the Michican Arrow add that I posted, Post#34, from around 1954 that they redisigned the outer shell using horizontal sheets with expansion joints to correct the problem.
