Simon,
It was only some of the UO-8s and a few of PR-10 Peugeots that I saw with the seamed forks. The PR-10 models had only the 3 main tubes made of Reynolds 531 and no chrome on the rear triangle.
We used that as a selling point for Gitanes and Bertins vs. Peugeots.
From what I've read a letter 'N' in the model number indicate that the bike came equipped with clinchers rather than tubular tires e.g. PRN-10, PXN-10 and so on.
For those of you who haven't seen this, there's a great page on PX-10 history on the CR web site:
