Up for sale here is this huge vintage Ward Leonard gray enameled power resistor.  It is marked RW47G450 WL 8597124-854, presumably a 45-ohm resistor, and tests right around 45 ohms.  This is a HUGE one, and I am guessing it is rated for at least 200 watts from the size.  Please see my pictures for details and dimensions. 

US shipping and handling is $10, and international is $28.  If you have any questions, please ask. 

I have more resistors and other vintage electronics listed--feel free to take a look!
