Early 70s PX-10 with a PR-10 Fork

@MiloFrance I've never seen a Vélo Jaune (yellow) PX-10 before except for some pictures I found on the internet from Europe. I remember seeing one or two yellow PR-10s BITD.

The paint is beautiful, is it a respray?

Here's a yellow PX-10 that was listed on eBay. None of the components are original and I suspect it's a respray because it has Nervex Professional lugs that were discontinued in 1972 with "modern" decals like on your frame. Those decals first appeared in the 1974 European catalogs and the 1975 US catalog.

As I mentioned in a previous post, PX-10 decals were available to Peugeot dealers except for the Reynolds 531 stickers so going by the decals is not always accurate.
@rjhammett I'm going to stick with my first guess based on the lugs and the serial number that your bike is an early 70's PX-10 with a PR-10 fork.

Here's how to tell about the fork:

The fork blades on Peugeot UO-8 and other lower priced models weren't made of tubing. Instead Peugeot developed a process of rolling sheet metal into a tapered cone, forming the rake and then brazing the seam at the rear of the blade. PR-10 fork blades were made the same way.

It's a little hard to see the seam in these blades because the they've been smoothed and polished. On some bike boom Peugeots the seams were more noticeable.

The seams are more obvious in this view of the top of the blades. Also, Peugeot as well as Motobecane and other bike makers used steerers made of straight gauge tubing with a split sleeve brazed in to the bottom instead of a butted steerer tube - see arrow pointing to split sleeve.

The way I first discovered the seamed blades was back about 1974 when I was trying to straighten a fork on a UO-8. I put it in a fork bending jig and the seams split like a banana!

I've never seen one of these types of forks fail except when crashed. Millions of Peugeots had these forks and people testify how great old UO-8s ride. So if you have one of these forks, I wouldn't worry about it. Ride and enjoy.
