Spanner Wrench Slotted Flat Key NSN 5120-01-026-3402 Hatch Tee

military-spec spanner that was designed for removal of engine hatches.( I’m guessing tank.) It has a slotted head, like a giant flat-blade screwdriver. The driver blade measures 1-1/2″ long x 5/16″ thick x 1/2″ Tall. Looks like a industrial valve shutoff tool. Handle is 11″ long and 10″ across the tee at top.
