I have an early 1950's Hehr Standard Window.
Sometime In its sordid past an object hit the lower window hinge, crush inning a small portion of it.
Also in the last picture you will see a hinge portion from another salvaged window. It was broken in half and only the above was useable
Can I graft the good hinge portion to the older frame?
I know aluminum is not responsive to major metal movement, no memory like steel.
Other than plexi, gaskets and screen, it seems useable.
