12" Dayton Tab Foot Type 50 Brass Desk Fan.  This is a nice complete Dayton Type 50 with brass blade and cage.  The finish appears to have been an older repaint but has held up well and displays nicely.  The blade appears to have been polished at some point and the cage has a little darker patina.  This is a nice complete and running example.  Switch appears to be nice and complete with only a little chip missing on one corner which doesn't effect its stability.  Nice solid early cast iron fan!!
