Single/double trees are attached to horse/mule implements by a clevis.  Some companies used their implement wrenches as the clevis pin. The pin would go through the implement beam and be there if you needed a wrench.  Here are 3 clevises with their wrench pins that I photographed on John Tabor's (TOOL TALK Johns48B) display trailer before he died.
