This is a latter model than the 820. This was built in the mid 40's. I know that they are the same model - I THINK they MAY be the same truck. What you cant see entirely from these pictures is that both trucks have similar markings. Note the Nation Wide Moving above the cab. Also in pictures I have, the logos on the bottom of the sides of both vehicles are the same. I would argue that they are the same truck - until PROVEN wrong.
