Photos attached. The catches are integral with the upper window (i.e., no easy way to remove it, except from the inside).
I could: replace the latches only. I can see there might be a few that might work, but I'm not sure what will "catch' properly.
Or I could put new latches in. If so, there is not enough horizontal space on the upper window to attach a Pella style catch--it's about 1/8 of an inch or so, not enough to support any kind of screw mount. Sooo, if there was something with a vertical mount, maybe that would work. If it exists.
If there was something in white, that might be better. But if the first option is better and those brass/brown colored ones are the only option, I'll live.
