This is a VT fuze of the ring type, similar to the T50E1 series. The VT Fuzes T91 differ from the T50E1 group in that they have greater sensitivity and are specially designed to be used for low-level, medium-level, dive, and toss bombing. These ring-type fuzes are especially sensitive to “passing” objects and therefore are useful in defoliating by blast and in getting roof-top bursts in city areas.
