NOS Antique Vintage Cast Iron Flanged Timing Pulley? 5" Dia. Industrial Steampunk Decor

Not sure what exactly this is for the teeth do not seem to be very deep to be a timing pulley but there are 28 teeth
 This pulley is from the Woolrich mill in Woolrich PA. it closed a few years ago.
Pulley is approx. 5" dia. belt surface is 2-1/2" wide the flange side is about 6-1/8" dia. the bore is 13/16" dia.
 
 
This is surplus to a now closed factory that kept spare parts on the shelf. The mill still had some of the old parts for some of their old equipment.
