Massive 12"x61" sine plate / fixture for a milling machine or surface grinder

Description

This is easily the biggest sine plate I have ever seen in my career. It is 61" wide and 12" deep and about 6.5" tall (top plate is roughly 4" thick and bottom is roughly 2.5" thick). Weight is estimated in the 1100-1200lbs range. It is covered in M16 threaded holes on all surfaces for work holding options.
This appears to be an unbranded shop-made sine plate and it seems to be constructed of tool steel. It has no damage or milling marks at all, just some scratches on the surface from normal use.
No shipping, this is pickup-only. I have a forklift and I can load this on your truck or trailer. I have priced this at LESS than the estimated raw material price alone, this is an incredible deal for someone with a milling machine or surface grinder large enough to use it. Make me an offer.
