While doing a bit of clean up, while waiting on gas meters to get changed out (inside old one, for a new outside one) Found this little gem...

Down on this end, there is a N O 2 stamped..and a GEO WORTHINGTON CO from BUFFALO NY..
Even my smallest chuck key I have, will not fit this tiny chuck..

Chuck works fine, but, there is no key to tighten it down on a bit....

Any clues as to what this WW2 tool was...and where a key would be found?
