Super-long for torque, thin for tight spots, Loc-Rite broaching for grip, and has the box ends extended for reaching recessed aircraft engine bolts. Originally had a black oxide coating.
Great find!
I have a box with many aircraft machinist tools useless to me. Been following a few auctions on eBay but they are not selling. I will post a few pictures later.
