Hi!
I have a bay window with two panes that open with a crank.
The handle of one of them broke. It seems that the "screw" part that the handle is rotating doesn't want to hold onto a the "gear" part that opens or closes the window.
Is there a part that I could replace to fix that?
I attach some pictures that I hope will help, including one of the one that still works.
The brand on the handle is Nuprime.
