Attached are 2 pictures of the metal knobs which go on the outside sill. (there is a screw driver slot on the top of the knob) and 3 pictures of the plastic piece which goes into the outside window frame.
The bottom of the screen has 2 holes which fit over the knobs on the sill. The spring pins on both sides of the screen fit into the plastic parts in the window frame.
some knobs and plastic parts were lost during reconstruction of rotting sills and frames.

Apparently a tool is used on the window frame to gouge out a hole in the wood, and the plastic part goes into the hole and is flush with the frame. It is not a clip.
Then a spring pin on the screen fits into the plastic part in the hole. Thanks anyway.
You do not have the metal knobs which are screwed into the sill? There are 2 knobs on each window sill. The bottom of the screen has 2 holes which fit over the knobs.
