I know my parents were there and I may have been there too. My father ordered a blue MG that was delivered in Sydney Australia in 1949. He did consider the Morgan but decided against it because he was worried about the durability of the wooden frame on the rough Australian roads. Considering the photos of the Australian '49 Morgan just restored in another thread I wonder what he would think about the wooden frame now.
Unfortunately no MGs or Morgan's that I could see in this film clip.
