Happen to have one in front of me at this moment.  J C Kupferle in St Louis  made them along with the majority of the fire hydrants sold nationwide.  After much research, it was identified as a revolving countertop nail display. I use it to hold nail clippers, aluminum can tabs, preferably the red ones with the crown cutout, chunk change and such.  I can see where it would come in handy in a shoe shop to keep an assortment of nails within reaching distance of the shoe last and cobbler's bench.
