Our local window place has been unable to locate these latches. Help us please from late 1970's to early 1980's we think.

This is definitely an older style latch, but it appears to be a match for our 26-015. Look it over and let me know if you agree, or if you had any questions! We also sell the 26-016 spring, if you also needed that.
