Power Transformer 195 pounds

I don't know much about this but it is a JEFFERSON electric power transformer ,It weighs in at 195 pounds.
ALOT OF COPPER WEIGHT I guess .
It is in good useable condition .
If you look up the model number 411-0161-000 it comes up with a new price of around 1,700.
00 dollors for a new one.
I wonder what the shipping would be? LOL.
