..another question what is the exact purpose of that little pin..

To facilitate mounting the wheel; mounting the wheel on the pin aligns the holes in the wheels with the threaded holes in the drum. Chrysler and others used the same method for many years.

PS - removing the "pin" will of course upset the balance of the brake drum. It's close to the center so the effect is probably quite small, but you might want to consider at some point having the tires and wheels balanced WITH the brake drum to restore whatever imbalance was created by removing the pin.
