White plastic Window latch

Hello!

Would it be possible to see an undamaged latch removed from the frame? The "tooth" on your latch appears to be broken off and that's an important detail. I should mention that there's a good chance we may not have a replacement for this part. Unfortunately, storm window hardware like this is a dying breed which makes it hard to get a hold of parts like this but seeing an undamaged version removed will help us confirm. 

Thanks for reaching out to us. The best possible match we have on our site would be the 91-054. This does appear similar to your original but it's still not exact. I cannot guarantee that this will work for all the reasons Emily stated, but it may at least be worth considering. See what you think.
