Cascade window cam latch

I'm afraid I don't recognize this latch. We may have something that can work for you, but before I recommend anything I'll need two dimensions:

• The distance between the installation holes, center-to-center.
• The distance from the hole centers to the back, glass-facing edge of the lock.

I'd also like a clear picture of the sweep itself, which is currently obscured. With that data in hand I will do my best to find you a match.
