This post documents the restoration of the S3 window, original to the addition put on the 1950s.

Here are some pictures taken before deconstructing the jamb. I pulled the casings off the jamb so that I could get the pulleys out.

And a picture of the knot used to hold the sash.

The jamb was pretty rotten on one side.

It was repaired with wood epox.

The left jamb was also split at the slot for the parting bead.

The hardware was soaked in a crockpot and paint removed.

The jamb was primed and painted

Bronze weatherstrip was installed in jambs and silicon bulb was installed in sill and head jamb.
