Where is the TT to be sited?
Wall/Shelf for a Solid Plinth like a Rega or Floor rest unit, where a suspended plinth might be a better choice - Lynn/System Deck.
And the thing with a Vintage... it may of fallen out of favour some years before being sold... like my Rega Player 3 / ATF5 Stilton that has been in the loft for 18yrs, so factor in at least a motor and spindle bearing lube and a belt(s)
