I bought this at the MVWC auction last fall just to get the wrench on the lower right. It is a double socket wrench (somewhat like a trombone) that was used to both hold the bolt head and tighten the nut on Model T oil pans. I intended to take the display apart, but never got around to it and thus decided to just hang it on the wall of my shop. Only paid $35.00 for it as few have any interest in the fixed socket wrenches.
