door lock

Hi Adrian,
I've got an old aluminum frame sliding glass door on a building, and the lock broke finally after about 25 years. No brand-name on the door.
I tried to find a replacement lock (non-mortise) but sofar I'm out of luck.
perhaps you or your viewers can help me to find a replacement lock? I offer a $50 finder's fee for the correct lock, if this is allowed.
Photo odf lock with specs/dimensions enclosed.
Please help;
Thank you from
