Top and bottom sliding glass panels I believe it is an aderson emco sold by home depot. Need replacement window latch

Ah, I recognize this. I have used our 91-183 as a replacement in the past. The dimensions are not the same as yours, but it was the closest match I could come up with. You may want to contact Emco directly if you want to get the exact latch.
