The nameplate is missing on this breadboard. I checked out Thorlabs, TMC, Melles Griot and Newport for this size and Newport is    the only one with the 1.1" thick Stainless version, or was, they stopped making them last year.  Unit is magnetic Stainless steel with plenty of 1/4-20 tapped holes.  I will build a shipping box for it at my expense. I'm guessing this to be about 75 pounds. The box will add another 15-20 pounds.  I combine ship as well.
