Viking crank and latch

This is always a tough situation. If the casement lock is locked tight, and the handle breaks off, there isn't a lot you can do. First, get a screwdriver and stick it in that hole to see if you can manually unlock it. If not, the only other method left would be to find some way to cut or drill it off the frame. This is not an easy project, so be warned!

Either way, once we can see the casement lock off the window we can do our best to find a match!
