Locking mechanism on a viking window

A contractor from Los Angeles says:
Hi,
I found everything else I need to repair 6 Viking windows on your site but I can't seem to find the locking mechanism. I found the latches but there is also a slit on the side that has a little knob and a pin that comes out to lock the window for extra security when it is closed that I can't seem to find.

I don't think Viking still uses this type of security for hurricane windows. See if you can use our 91-179. This may be a possible replacement.
