Some type of barrel tool?

The threads look like they may fit a steel barrel? don't have one handy to try it.

Huh. I've never seen one of those on a barrel before. Never seen one anywhere else though either.

They made more than one, someone else is wondering what it is for.

Pg 3 of the Sept. 2009  MVWC NEwsletter  shows the drawing for  patent 2,543,151 ( http://www.datamp.org/patents/displayPatent.php?number=2543151&typeCode=0 )  Combination Bung Plug & Agitator Crank.   The crank  was for an agitator inside a steel barrel, to stir the contents before pouring some out.  The threaded portion fit the "bung" opening that had the stud end of the internal agitator.
