This mechanism is used to open, close and lock the bonnet. With a cable, operated from the dash, this mechanism can be released. To prevent the bonnet jumps open during driving an extra hook is mounted which must be pulled forward by hand before the bonnet can be opened.
The metal strips between the bonnet and catch plate are installed to divert the air flow. The radiator is only 16″ wide while the opening in the grill is only 8″wide. The “air deflectors” should make it possible to cooling down the whole radiator surface. This was not an optimal solution because most cars suffer from overheated cooling systems, during hot summer days.
