Faceplates, around £30 -£40 each
Chuck, £50 or so, depending on type ( looks like a metalworking chuck but still very useful for holding home made screw chuck, pin chuck, drill bits etc). If it's a wood chuck plus jaws then probably worth £150 or more
Revolving centre, drill chuck, bowl rest - easily worth another £50
Sanding table, I have seen these fetch £80 on ebay.
Chisels included - got to be worth £10 each, possiblity much more depending on type and make
Plus everything else you need - no need to search for bits such as rests.
I know the final value does not always equal the sum of the parts etc, but you could sell on surplus faceplates and get over £100 back easily I would expect.
Question - why has nobody grabbed this? Sounds like a very, very good deal. I love my graduate, and if I didn't already have one I would buy this, no hesitation.
