OLD sliding glass door lock

The lock is very sloppy. I was hoping for more security, but nothing comes close to this lock set. I installed a Wright surface mount set, but it is cheap at best. After searching the web for hours, I found nothing close. There is a set of numbers stamped at the keyhole: T102. could even be F102. The house was built in 1962.
