Yes, 72, 73 and 74 were a situation where the police had asked me to reconstruct the way in which the Pine Parkade device was made up and they used a replica, or empty rather, demolition charges, SZ3 and SZ6s.  So they were actually empty.  Although 75 appears to be a genuine handgrenade detonator, the rest of the stuff were all replicas or empty.  I don't think they would have allowed me to come too close to live explosives.
