So my acquaintance found some more parts for the David Bradley. Here are a few pics.
Her email said, "My daughter and I were moving everything of any value down from the upstairs storage today, such as all of the business receipts and came across the DB hood and a hook on cultivator piece, plus some extra pieces that may go with it. Also found this green tractor radiator and ??? heavy metal part. The radiator is a Modine MFG Co, Racine Wis Model AD or AO (couldn't tell) -323T-109. On the bigger heavier part was L520T. I need to clean the pieces a bit to see more, but way too busy today."
And something else for us to ID.
