These were purchased at a lost freight sale earlier this year, and they are brand new in the original factory boxes. These are not equipped with a standard roller lever (part number 24-1712), but a variety of levers are available from Eaton suppliers.  Best we could determine from Eaton's website, these are the same switch as a 10316H18, but without the roller lever, and with the addition of the information sheet (picture #11). Super rugged switches, with a weight of over 3.5 pounds.
