So with a search for a speeder, I found a bit more:
“Fulton 4-Way Socket Head Speeder Wrench 1922. An antique Fulton Tool Co. 4-way socket speeder wrench, sized 5/8 11/16 3/4 and 7/8 inches 6 point sockets.
Gentlemen, I've had this sock head for 20 years, garage sale find. I've used it to level up the camper trailer. I have no idea of its history, manufacturer, nor intended uses. Any ideas on this beauty?
