I'm not big on parting bikes out, but as one restorer I follow says "they are lots of old French bikes out there but not allot of French parts" I am guessing the chain-guard, pump and flag all have value due to their time capsule appearance and as anyone who has worked bike boom era Peugeot's will tell you an intact front derailleur is a rarity lol. Its gorgeous, you just don't find mint bikes like that everyday, and it would be great if someone could ride and appreciate it. Split tube mixtes have gained quite a bit of appeal in the last 5 years or so -I have a Taiwanese built Raleigh mixte in the queue and its in good shape but not mint like your Peugeot. Great find.
