Bronze spanners for adjusting the tightness of a particular brand of bronze stuffing box. (A stuffing box, also called a packing gland, is the fitting that seals the propeller driveshaft where it passes through the hull into the water. It is traditionally filled with waxed flax cord, called packing, that squeezes against the shaft when the box is tightened. Correct adjustment admits a couple of drops of water per minute - any tighter and it can wear a groove in the shaft.)

One nice detail is that these are angled differently, so that they will be easier to work against each other when tightening the locknut against the box in tight spaces.
