Antique Enterprise Sad Iron (missing part)

Antique cast sad iron with wood handle by Enterprise Mfg Co Philadelphia No. 50. Missing the wooden knob that goes over the nail in the middle.
Trendy ideas for antique irons include using them as paperweights or doorstoppers!
 
This iron has not been cleaned and so retains its original rusts and crusts!
 
NB. I am no antique irons expert, and have tried my best to describe each one. Please see the photos as they show more detail than I can provide :-)

Dimensions: 17.5cm long, 9.5cm wide, 12.5cm tall.
