casement window lock handle

I have 4 of these casement windows with this flimsy plastic handle to operate a vertical sliding lock bar to lock the window. All of them have broken over the years.

If you know of a replacement or alternative I would be happy. I looked everywhere online. I found the replacement top and bottom hinges and crank mechanism that has rusted on the bottom.

Thanks ! I found the item on your site and ordered 4 of them
