Carrier tools- 3/8"x11/16" box end wrench
 

Just going thru the carrier tools to see what I have against the carrier tool list, and need to get a clarification on a box end wrench listed:
-CO 1UC 100744 wrench- 3/8" x 11/16" box
Is this the correct size, or is there a size mistake? Should it be 3/8" x 7/16" box, 5/8" x 11/16" box or 3/4" x 11/16" box ?
Was there a wrench made like this, if so, does anyone know who made them?
I can`t say that I have run across this wrench size. It is never to late to learn. Your help and knowledge on this would greatly be appreciated.
Thanks,
Doug

Doug, that is a misprint in the parts list. Here is a pic of the two box end wrenchs as issued. Hope that solves the question/mystery.
