Sliding window locks needed

A home owner from Florissant MO says:
I have three single pane aluminum windows that slide horizontally. The city requires the windows to lock and these no longer do. Can you identify what replacement parts I should order? Thanks for your help!

Dave Sr. from SWISCO responded:
Your window are very old and the replacement parts are hard to come by. We do still have locks however, it is the opposite hand, it could still work for you. It will be very difficult to install, maybe try using a 3/16" pop-rivet and a small washer under the lock so it will turn smoothly to lock the window.
