Peugeot Freres (Peugeot Brothers) wrench & Thiem Aircraft fuel filler nozzle -- Before & After Cleaning

The same family of businesses as the Car company (company goes back to the early 1800s).  This type of wrench design places the force on the face of the hexagon, not the corner tips.

Commercial aircraft under-wing refueling nozzle.  Made by a company called Thiem which got bought out by a company called Maggitt.  This basic design is still available and about $1,500 ~ $2,000 new... (didn't take a picture before cleaning...)
