I have a VGC 2088 bridgeboard with VGC ISA floppy disk interface card, cables, original manual (VGC) and 5.25" floppy disk drive.
The disk drive is the original one supplied by Commodore (in the same matching grey as the face of the A2000), and is only very slightly discoloured. A quick dose of Retrobrite would have it looking like new.
Not sure if this is any good to you, but if it is please feel free to PM me.
