Can anyone tell me how to find the history on this part? On one side in raised cast letters it says "The Studebaker Corporation AA4855". On the other side there is a B inside a triangle. The wrench is about 9 5/8 in. long. On one end is an octagon about 1 13/16 in. across outside. The inside of the octagon is just round. The other end of the wrench is a hexagon with inside and outside dimensions of about 7/8 in. and 1 3/8 in. respectively. I would like to find out the actual applications, period of manufacture etc.
