On blogs elsewhere on the web, there are a few other designs, mainly for screen doors. Since every house is different, and since I couldn't locate any photos of actual original wooden window screens on the web or in books when I was trying to figure out whether I could make my own, I have photographed three other screens that I found in the basement.
They don't fit any of my windows (so then, why are they squirreled away in my basement? Who knows?), but of course I kept them, like some other pack rat before me, and they might be helpful to others.
For each of these, I subsequently went back and did posts with close-up detail for each, with links below.
Alternate Model Number One:
Here is one that is made without mitered corners. Stuck onto what I think is the back, on the top, is a very different kind of bug stop, a header of beadboard. Perhaps used to hang the screen? Or to slip up underneath a half-storm? Maybe as a part of a two-part screen for a double-hung window? I don't know.
