1933 Raised Hood Catch

[FrankWest]

When I lift up my hood it sometimes catches and stays up and sometimes slips down. What should be there to catch the hood edge and hold it up and keep it from falling?
Perhaps my hood sections are connected together to stiff and do not fold over far enough, I lubricated them hinges with Gibbs oil and folded them over more and now it seems the center of Gravity back far enough to keep the hood from falling down. Is that they way it was intended to work?
