Just spotted on the bay, might interesting old 3/4 drive open ratchet, under collectibles.  http://www.ebay.com/itm/Antique-Old-Tool-Open-Ratchet-Tool-Wrench-Open-Gear-Square-End-3-4-50667-/231445621553?pt=LH_DefaultDomain_0&hash=item35e33beb31

"MUELLER" on the handle end suggests it was the ratchet handle for the drill in a MUELLER water main tapper.

Or a wrench for tightening up gland nuts.  I have one I bought for working on underground pipe. When tightening up all-thread rod it is nice to be able to have a long rod go through the wrench.
