ANSI/AAMA-101-88; Series 8000 and MVI Manufacturer's code.
The latch that slides into the window groove to lock it has broken off and the window can no longer lock. I can find no other markings on the latch other than the name Masterview.
The latch itself is 2 7/8 " long and 3/4" wide. the screws that hold the latch onto the window frame are 1 7/8" apart.
