trying to replace window latches

A home owner from West Milford, NJ says:

We moved into our house two years ago; in that time, the latches on about a dozen windows have broken partially or completely. The metal seems very brittle and light-weight, and the windows are probably a few decades old. There are two latches on each window, and we have no idea what brand the windows are (they have no info etched into them, for example.)

I tried picking up replacements at a nearby Lowes, but the smaller piece - the piece attached to the upper window - was too deep on the ones they had. As you can see from the photo, on ours it is less than 1/4" deep, and I haven't found a match.

We're hoping to replace some or all of these this fall, as the windows don't seal well without them.

Thanks for posting! Before I offer any suggestions, could you please tell me the distance from screw-hole to screw-hole in inches? This will help us narrow down the search for an applicable replacement.
A home owner says:
The holes on the inside/lower window appear to 2 1/16" apart, center to center. On the outer/upper window, they are about 2 1/8", slightly further apart.

I think the 90-161 White Window Lock and Keeper should work on your window. We also have the 90-077A Window Lock with Alignment Lugs, and its 90-177 Window Lock Keeper. The 90-077A is a rectangular lock, but it comes in different colors.
