This is the exact handle I have been searching for. It has been a years long search. It fits 1957 aluminum windows.
Is the pivot a through metal pivot, not a screw? The cheap replacements have a screw pivot that either breaks or backs out with use.
Does it come in right and left versions?
My originals are either breaking at the pivot or the mounting plate due to metal fatigue, not unxepected whenever 50 years old.
