Window sash latches

Question

These latches are on 22 year old Marvin double hung windows. The center to center measurement on the large piece is 2 1/16...other measurements are in one of my photos.
The only markings are on large piece. It says "lock". There is a patent number underneath. 5.110.165

We believe our 90-318 window lock and 90-279 keeper may work in place of your current window parts. Look over our measurements to see if these are the parts you have been searching for.
