Looking for window sash lock

Question

Hi, I have ten of these windows, no markings, wood window frame - but the horizontal beam across the bottom of the top window is flat, then steps down twice. Some of the windows slip open, and I want a way to make sure they're closed for the winter. Any ideas for what hardware that might fit?

I believe I can help you with this. Take a look at our 90-095 Andersen window lock. This keeper is made for wood windows that has a top sash angle trim such as yous with a cut out for the vertical mullion.
