PX 10- two questions
1. Head badge has 2 rivets (gold lion-red badge thin steel)
2. Simplex down tube shifters are 2 piece steel (w/black plastic ends and wing nuts)
I can't find these things on other pix of these bikes, of course tying to pin down the year (rear de-rail Simplex prestige has 70 stamped on back)
White (531 doubled butted decals) frame w/black Nervex "fancy" lugs (gold pinstriped)
Chrome fork ends and rear "triangle" Brooks Pro, Stronglite, Simplex, Mafac etc.
Should be a PX 10

1 and 2 are facts. What are your questions?

On PX 10 questions....
Standard answer 1) No, it's most likley a UO8
Standard answer 2) No, It's most likely a UO8
Just kidding....
Frankly, I never really could nail down how to spot a real PX10
Grand Bois and Maimijim are the PX10 gurus here!
All I know is 531 tubing means you are getting close....and maybe a silver Simplex label on the RD helps...

Right no red on the RD and no plastic de-rail cable guides near BB and cool black and gold Simplex badge on seat post. Then the big TROUBLE is the 5 digit number stamped on the BB

Jim's PX 10 in the vintage for sale section is a great guide to some PX10 features.
+1 When it doubt, just say three times: "Its a UO8, its a UO8, it a UO8".
In your case, it certainly sounds like you have something MUCH nicer than a UO8.

You don't have the chrome on the rear on the UO-8 and the 531 decal on the seat tube. Why can't I find the 2 rivet head badge, is it possible this was not an export machine?

It actually does sound like a PX-10. I think only the PX-10 had chrome on the rear triangle.

Sure you do. My '72 UO-8 does. You want to distinguish a UO-8? Measure the length of the chain stays. It will be 18 1/2 inches or more. Unless they shortened it.

UO-8 was double-butted? I didn't think so. I just spent a few days trying to nail down how to spot a real PX-10 (and deemed the one hanging in my closet as a "real" one).
I can help you nail down the year I think. Where is the Reynolds sticker? On the seat tube or the down tube? Seat tube = pre-1975 and on the down tube = post-1975. Or, maybe it's 1974, can't remember. But that will help you get close.
Sounds like yours is a year or two off from mine. Mine is identical to yours aside from the "fancy" lugs. I have the same Prestige derailleur, chrome stays/bottom fork, etc. Mine is either a 1970, 1971 or 1972 based on the plain lugs. Yours may be a 1973 or 1974 if it's got the decal on the seat tube.
At least you have a real PX-10. That's really all that matters. My GOODNESS these things are hard to nail down.

My PX10 ( below ) has the same DT Simplex shifters and 2 rivet Lion thin steel head badge you described.
It is still awaiting restoration, and has type II decals, an AVA "death" stem, and a Simplex Prestige DR which I believe puts it between 1970 and 73.
I can't get it any more exact than that.
( BTW the blue paint is original. I don't think it was cataloged though, and I've not seen so many blue ones. )
So where is a picture of yours?

It seems as if plain lugs were more prevelant around that time but I've seen them before and after as well. Keep in mind that there are many lug combinations ranging from full fancy Nervex lug work to full NON-fancy lug work and every combination of the 2.

Yes, but we won't hold the extra letter against it.
