Vintage awning window hardware

A home owner from Atlanta, GA says:
Hello, we have recently purchased a home built in 1956 with original living room windows. The top windows are awning windows and currently just have screws where some kind of push bar was attached. See photo. There is a hole where I assume this bar would go through, along with something that looks to be a sill-mounted keeper. Any help identifying what we need would be wonderful. Thanks!

Based on the age of the window, there's a good chance that the part you need has been obsolete for many decades now. The only product we sell that works in a similar fashion would be our 39-370, but even then there is no guarantee that this will work for you. Look it over and see what you think.
