Jack,
That's an interesting time line that Kim posted but it doesn't quite jibe with the several months of research that I did on my 1967 PX-10.
That's why I made a comment in an earlier post that the catalogs referenced were French and Dutch.
I didn't have time before to find the links to some other sites with Peugeot catalogs that I used in my search but here are some of them.
Here's a link showing 1966, 67 and 68 French Peugeot catalogs without any specs. The bikes all have small flange hubs.

Here's another site with a bunch of Peugeot catalogs:

Here's the specs for a 1968 PX-10. This lists the rear derailleur as a Prestige 537 Luxe which is probably incorrect. By 1968 it should have been a black badged Criterium:

By 1968, the red label Prestige derailleurs were the cheap models. I suspect that at some point the original (probably black label) Criterium derailleur needed to be replaced. Quite likely the LBS who replaced it didn't have ready access to a Criterium derailleur so they used a Prestige instead.
The Criterium was the premium model Simplex derailleur by then and only came on top quality French bikes with Simplex dropouts.
I've seen a few Criteriums with a "claw" attachment but never I've never seen them listed in any catalogs.
Here's the Criterium page from the 1971 Simplex catalog:

Even in the 1970s replacement Criterium derailleurs were not that easy to get plus they were expensive (I'm thinking about $18).
My 1967 has a 1973 Criterium RD. I'd like to get a good black label Criterium for it. Only about a third of the Criterium derailleurs that I've seen have a date code.
I've seen a few PX-10s with black seat clusters and BB but most have been white.
Supposedly all PX-10s made for consumers before 1966 were blue with the early one having yellow lugs then later black lugs. I've seen at least one white non-team pre-1966 PX-10 so who knows.
Some of the Peugeot team bikes were all white with no black trim.
Peugeot produced both riveted and glued head head badges from that era.
The standard pedals for those years were the Lyotard model 45 alloy quill pedals. The Berthets may have been changed by a previous owner. I have very wide feet so I've used Berthets or Lyotard 460D alloy pedals on my old French bikes.
I always thought that the Simplex left dropouts with the "horn" were discontinued by the end of the 60s. The 1971 catalog shows the Ref. 1753 with a horn. Of course it could just be an old printing plate that they never bothered to change. same thing with most catalogs from those days. They were hand laid out with cut and paste methods and the type was handset.

There's a wood plug in my steering tube too.
The serial number on my 1967 PX-10 is 483675 and your later model is 200631. If you look at the serial numbers on the CR PX-10 page you'll see that they jump all over the place so I don't think that they mean anything!

BTW, In my research on my 1967, I ran across very few 1968 PX-10s.
