This is one of three hinges on the door between the cockpit
and the salon
on my Prout. The top one broke when my daughter hung all of her weight on the door this weekend. The real cause of the failure was a poor casting. There were a couple of large occlusions at the break point. It is a two peice hinge and separates similar to the way a rudder
is attached on a small boat. It's chrome plated bronze.
