Older casement windows--insect screen attachment?
I'm in the process of mildly restoring the casement windows in the sunroom of our 1927 house. The windows are in fine mechanical shape, though I'll be doing a lot of reglazing this summer.
With the approach of spring, I'd like to get screens up. The problem is that we do not have any of the original screens or frames. I can build new ones easily enough, and have done one already. But can anyone look at the photo and tell me what sort of hardware I should be seeking to actually clip the frames into the window surround? There is a hole on either side of the window jamb, about midway up the window. The hole is just inside the edge of the frame where the screen fits.
