  I opened the box for the first time to inspect and take pictures.  The cup is in brand new, never used condition and is free of any damage.  It is still greased from the manufacturer.  There is a spot or two of extremely minor surface rust from many years of shelf storage. May or may not need a light polishing up before installation. The original box is in good condition.
