I bought a '63 P13 Deluxe a few years ago, most was correct except for the brakeset, stem and bars. No wheels. In that condition I paid $500 for it, and it took me half a year, probably another $500 and a lot of luck to gather the correct parts together - especially the Titan stem and Maes/Kint bars. A grail bike so the total was worth it to me, had I paid the seller more it would have edged into not-so-worth-it territory.
In it's current condition it's worth at least what I have in it depending on the buyer (Not planning to sell). Your specimen appears to only have the correct crankset, the rest is a hodgepodge. Not sure about the condition of the chrome, pictures can be deceptive on that - headtube looks a bit iffy and that headbadge has seen better days. Per Juvela It'll take some work and $$ to set it right if that's your intent, something to keep in mind as you move forward.
