How can we answer without seeing pictures of the bike in question?

But of those three options, A seems most reasonable: With Option B the buyer has extra work deciding whether they want a vintage-correct Torpado (a marque without major name recognition) or to strip the frame themselves to start with a blank canvas and/or deal with sales of vintage parts, and option C you end up with a bike sitting unused for extended periods. With option A the frame goes to somebody who will use it immediately and you're set with a complete set of components to use elsewhere (much easier to store than a complete bike).

Only thing I might suggest is that including the headset and seatpost with a F/F sale would be nice, it makes it easier for a potential buyer to start imagining possibilities within easy reach...
