Yes, a single s in old German script does look like an f to us, although the German f is formed a little differently as you will note later in feld. She is a widow at Castellfeldgasse. There is a street Kastellfeldgasse, 8010 Graz that exists today. The c and k are interchangeable. Kastell means fort(ress). Looks like her husband was a gendarme/sergeant.
