Bluerf as the cabinets are nailed shut, what I am going to say must be pure speculation based on thier appearance, the majority of spines appeared to my eye to be around 10mm or slighty less & with distal taper so they would seem fast enough for the Gurkha approach to battle.
Several had spines of up to about 14mm & one looked nearer 20mm & presumably was just used for fairly stationary targets! Or was used by a Arnold Scwarznegger look alike perhaps?
