When did the last pre-war FM station go off the air?

From JJ's Radio Logs, a Chicago Tribune listing for Feb. 2, 1949 is the last showing pre-war (42-50 MHz) FM frequencies. It shows WEFM on both 45.1 and 99.5 MHz. Listings after that show only the current (now WUSN) frequency.

Was this the last station on the pre-war band? Did the Tribune just forget to drop 45.1 until then (they listed their own WGNB, along with WEFM and WBEZ, on pre-war frequencies well into 1948)? If neither of those, what was the last station on that band to die?

I should say that I am not including the Armstrong FM station in New Jersey, which remained on the air until shortly after Edwin Armstrong's death in 1954. That station was always licensed as an experimental station, not as a broadcaster.
