| 8123. To SY. From Ha/Rm.{William Robotham - Chief Engineer} Ha/Rm.{William Robotham - Chief Engineer}18/MJ.9.12.32. We think the manifold studs on Peregrine are rather small. We blew an exhaust joint recently which we attribute to this fact. Would you see if there is any reason why we cannot get quarter studs at this point. Ha/Rm.{William Robotham - Chief Engineer} | ||
