Here is the nameplate from the transformer from the mill. It shows a rating for 400 horsepower machinery using a line voltage of 2300 volts. The transformer is for three phase at 60 cycles. I am assuming the unit dates from the 1910's, which is when the steam powered equipment was replaced with the electric motor drive. It's sad to see the old mill go, but at least I could save a little bit of it. If you have more information on the age or catalog images for this transformer I would love to hear from you.
