The early history of the crossbow

[petermac]

I would think that bone nut would roll OK round the pivot point. There is a small lip below, which the trigger bar would stop against. Being small, it should make it easier for the trigger to slip off when the lever of the trigger is drawn up towards the tiller or stock of the bow. The string would then slip off the top of the nut. It looks to me that the flat "bar" behind the pivot point would stop the nut rolling too far over and presumably would allow the bowman to flip the nut back, before engaging the trigger again.
