Yeah, pics of Morgans alongside a Shakleton seems very apt indeed.
That the Shakleton was described as 10k loose rivets flying in close formation, kinda fits well with the amount of flex and movement in the structure of a trad Morgan, never more than when yomping along an old worn B road with any sort of pace on.... Been there done that while bighting at the rear end of a very surprised 911 for just a few miles. I was much younger then..
