Acorn Brass Manufacturing Company (formerly known as Acorn Brass Works) of Chicago, Illinois.
Acorn Brass Manufacturing Company of Chicago, Illinois made this iron around 1913. It is unique in that the tank is the handle. This iron requires an external pump to pressurize the tank.
Iron information is on the end of the tank handle of this Acorn iron.
A different Acorn iron has Acorn being in Aurora, Illinois. Acorn opened a subsidiary factory in Aurora and produced irons there. This iron is not in my collection.
Patent by Theodore Prouty of Aurora, Illinois.
Acorn iron with pump built into the handle. This iron is in Kevin McCartney's collection.
Acorn iron but with a unique pump knob. Not sure if this is original or a replacement though it does appear to be very old. The pump knob kind of looks like a lamp finial. This iron is in George Kyle's collection.
