A very interesting projectile showing an early development stage in the Brooke ratchet system.  This specimen does not have true ratchets, instead three very broad flanges fit into matching notches in the projectile base.  The sabot is quite thick, 15/32ds of an inch.   The sabot, which is secured by a center bolt was probably too thick to expand properly.
