Part to fix front door on a '51 series 200

A few weeks back, the wind ripped the left front door out of my hands. There was a little sheet metal work which I've since fixed and repainted.

However, the little part that holds the door in the open position was damaged beyond repair.
So my question is twofold, 1) what is the part called and 2) does anyone know where one can be had or is there another that can be substituted for it?
