Storm Window Latch

Hello, Paul. I'm sorry to say that I can't determine what latch you have based on this photo. Too many important details are obscured. Would it be possible to see it removed? Can you also write down its precise measurements for me to review?

Please also note that while we do still carry a selection of storm window latches, we don't have everything. Storm windows have been dying off for a few decades now and parts like this are increasingly difficult to come by. I'll of course do my best to find you something, but in order to even begin we need to see the original out, and we need precise, written dimensions. Please let me know if that's possible.
