Adam,
Condolences about your father.
To assess the lathe, a few questions. Does it have power cross-feed? Are all the gears sound, with no missing teeth? Does the headstock spindle seem to be in good condition? (In the absence of more sophisticated tests, check that there is no disconcerting noise when running, and that if you chuck a stout bar 6-9" long, you can't feel any movement if you push/pull the unsupported end.) Is there any sign of excessive be wear (this will show up be a marked variation in stiffness as you move the carriage from headstock end to tailstock end)? Ditto for the cross-slide. If the answer to all these things is positive, then IMO £750 is much too low a price – by a factor of 2. Even without power cross-feed (and as best I can see from the photos it doesn't have it) it is too low. The gearbox alone would be worth nearly that much (I bought my gearbox new in the early 80's when I upgraded my S7 to S7B and paid over £400 then!).
Of course, that assumes you put in quite a bit of effort to clean it up. For a decent sale price, appearance is important; it suggest the machine has been well looked after. Sorry if I repeat what has been said, but (1) remove all traces of wood dust (if that's what it is); many kinds of wood can be corrosive. (2) Remove any other crud; use a toothbrush if necessary. (3) Go over all parts with an oily rag until nice and polished-looking. (4) Fill the oil cup on the headstock and oil the oiling nipples with the oil gun. (5) Clean up the acessories – many of them (except the 3-jaw chuck) look rather tarnished.
As to what to include and what to sell separately, then by tradition a second-hand lathe would come with 3-jaw s/c chuck, 4-jaw independent chuck, faceplate, tailstock chuck, two 2MT centres, some form of toolholder (the 4-way one on it will be fine, gruesome though they are IMO) and the basic spanners etc. Anything else would be a free gift to the buyer, who probably wouldn't end up paying any extra for them. Thus the swivelling vertical milling table, the tailstock dieholder set, the wood-turning tool rest and any other extras may as well be sold separately. The tailstock offset device looks so disgusting I'd bin it, but you may feel it would clean up.
As for selling, I don't like eBay, except as a buyer (when I have to go where the stuff is to be found). I'd be inclined to put a free ad in ME/MEW and/or on homeworkshop.org.uk. Stuff I have put on there has sold in a day or two. The only advantage of eBay is that you may – occasionally – get lucky if two bidders get carried away.
And finally, As someone else said, don't use WD40 – it's only uses AFAICS are for drying out damp car plug leads, and helping to loose stuck bolts. Use the slideway oil your father probably had somewhere about; Esso Nuto was the traditional one. And absolutely don't use 3-in-1 oil (yuk); it's only useful for garden tools IMO.
