The one thing that is done differently for reenactments is the actions of #3 (services the vent) and #4 (Primer and lanyard). In the original drill, when #4 inserted the primer, #3 would cup his hand over the vent to hold the lanyard in place and protect the primer/vent, #4 took the slack out of the lanyard, and #3 remained with his hand over the vent until the order to fire was given. then #3 stepped outside the wheel, and #4 was responsible for watching #3 and not pulling the lanyard until #3 was outside the wheel. this was done to protect the vent/primer during combat. Glad we don't do that now. one mistake and #3 lost a hand or was run over (or both)
