Peugeot PX-10 in Disguise?
Came across an old road bike that I think is an early 70s Peugeot PX-10. Its missing its head-badge and been spray repainted red, but the original white color is visible in some spots. Very little rust and the chrome plating is in excellent condition.
The tell-tale signs:
The tell-tale signs:
*Nervex Pro 49/162 lugset
*Chrome on lower part of fork and the rear triangle
*Seat tube diameter 28mm
*Simplex dropouts
*Seat stay diameter of 16mm at seat lug
*Simplex seatpost ~26.4mm
*Stronglight 49D crankset
*Stronglight Competition headset
*Atax stem
*Mafac "Dural Forge" brakes
*Normandy high-flange rear hub
*Atom freewheel
*Atom pedals
Am I correct in thinking that it is a PX-10? Not sure of the date of manufacture, but guessing early 70s due to brakes being stamped "Dural Forge" instead of "Racer". The serial number is also a bit of a mystery: 44273.

I don't see anything that says it's not, and I think it may be earlier than early seventies.. The bars, levers and cables need some attention. I don't think either wheel is original.

The front wheel is definitely a replacement with a Suzue hub and Araya red label clincher. Same for the back rim as it is a Weinmann clincher rim; at first I thought that the Normandy high flange hub might be original but then noticed that it has "13 79" stamped on it (which I take to be a date code). The plan is to remove all components and try to remove the red spray paint to reveal the original white.

The rear hub looks like a Normandy Sport, not the original Luxe Competition. If it were mine, I'd look for some Maillard 700 hubs. They're much better than the originals, which all seem to have pitted cones.

Looks like a PX10 to me. I love that Stronglight crankset. What are you going to do with it?

When you have it stripped down, you might weigh the frameset. That should help confirm the material. Compare it to known PX-10 frameset weights. I can weigh mine, as it remains in pieces. I'd bet it is a PX-10.

Based on the parts and lug work I would guess it is either PX/PY-10 or a Jeunet 640. The PX is the most likely candidate since it was the most produced sold high end French bike out numbering all the likely others put together.

Started to remove components and noticed that the Simplex rear derailleur has ball bearing pulleys and the back cage has "1 70" stamped on it. Assuming that the rear derailleur is original, I guess that suggests that the frame is a late 1969 manufacture and that the bicycle was built up in early 1970.

Just curios did the former owner manage to drill screw up anything other than the brake levers? This is a really nice bike I hope the drilling stopped at just the levers.

Yes, thankfully, the previous owner with the drill and the itchy trigger finger stopped after the brake levers! The drilling of the levers looks particularly amateurish; matches the paint job.

I believe it's a 1970 model, based on the derailer dating and on the use of Dural Forge calipers.
The Calipers and crankset could both be 1970 from other examples I've seen, and as zukahn1 pointed out, there was high production volume on these in 1970.
This bike's original head badge is riveted-on metal foil, with shield pointed on the bottom. Downtube "Peugeot" lettering is small.
These earlier PX10's had close to 72-degree frame angles, which makes for calmer steering and also makes the frames feel small for their size.

Rear derailleur needs the cage spring tightened to tense up the chain, and the front mech needs to be mounted lower, 1 to 3 mm above the large chainring. I'm not sure there's an issue with the handlebars, but I'd go through all the cables and at least square up the ends of the outer cables, add ferrules to them, and careful re-set-up them. I'd also take apart the calipers and clean every thing, lube the main pivots, and lube the points where the springs bear on the aluminum caliper material. If the shoes are ok, they will work like butter. Even better if you get a set of new modern inner and out cables and install with the same treatment.

The Simplex dropout hook for your thumb was used on 60's bike but also on my '71, and sporadically on bikes as "recent" as [MENTION=27118]Grand Bois[/MENTION] 's 1974 PA10. (The Dural Forge calipers and derailleur date suggest just a slightly earlier vintage than mine).
It's a good find, [MENTION=60110]leecycle[/MENTION] - one that I would seriously consider restoring to the original paint color with repro decals and stock Mafac levers. Wouldn't need much else.

The bike is very conflicting.
The only solid piece of evidence suggesting a date of 1970 is the RD...
1970 PX10 crankset: Stronglight 93 crankset. This bike has 49
1970 PX10 brakeset: Mafac Racer. This bike has Dural Forge
!970 PX10 decals: Square badge with a flat bottom. This frames rivet pattern suggests a the older triangle shaped badge.
Most of the parts look period correct and they look like they've been on the bike for decades so it gives the appearance they're original PX10 components. Its old, the frameset suggests '65-ish thought '74. The RD suggests '70. Other components do NOT suggest '70.
