In Ages Past, the N3F published other fanzines. Occasionally we find traces of one.
Postwarp was the N3F Letter Zine, back when members wrote large numbers of letters about the club. It launched in 1950, continued to the late 1950s. Some issues of Postwarp were published under the diminutive title Postie.
Postwarp was apparently replaced by Hyperspace Tightbeam, which after three issues was renamed Tightbeam. Tightbeam continues to this day, though few members now write letters.
