This is ok, but what it doesn't represent is how a real metal hinge is made, as a sheet metal object. This video represents a machined or molded version with no open ends as a real hinge is made as the knuckle rolls over.
TH-cam came into existence after 40's but you will find a lot of videos similar to ours. So we are not creating any unusual thing. We are creating content according to our strength and limitation hopes people will understand our point.

Is there a voice or is this a silent video .... I thought we had sound since the 40's
