It's all in the name - Solved by Ehhxekt, Allan L, ImpishGrin, Allemano and Paul Jaray

F16  Walter Owen Bentley - car 20 an unbelievably tarted-up Bentley 3 litre of about 1922

It appears on an internet site as a 1926 Speed model with a Barker body.
I'm not convinced that beaded edge tyres were still fitted in 1926 and I've never seen a Barker body that looked so strange, but there you go!

Right. That body deserved to be attributed to its true maker, didn't it?

[Ray B.]

Could it be 'Décapotable', then?
EDIT: Oops, this was a stupid guess. The car has a pillarless phaeton body. Phaetons are often called 'Tourers': is that the right word?

Not in France. This is a french car, remember. It's just for the sake of exactness.

[Allan L]

F17 Mercédès Jellinek - Car 4 1914 Grand Prix Mercédès

Allan: I'm not so good ad old Mercedes racing cars, so I guess you've got the year and model right. But from my source (and it seems a very documented source), the race is the1922 Targa Florio, and the car  La numero 38 , une Mercedes 28-95 7.300cc conduite par Max Sailer (6°)
The points are yours.

I still think it's a 1914-type Mercédès: at the Targa Florio in 1922 there were three cars based on the 1914 GP car, driven by Lautenschlager, Salzer and Mazetti.They had 4.9 litre engines adn four-wheel brakes (which was an obvious thing in your photo that I had not picked up!)
Mazetti won carrying no 40, but I can't find the other comp. nos.
What I am pretty certain it is not is a 28-95 (see below)

Oh, F9 is Count Albert de Dion and car 8 is a de Dion Bouton, perhaps a 12/24 of c1923

Allan, you amaze me. And as usual you seem to know more about the cars I post than I do myself.
Both answers are right, as for the car I only have that it's supposed to be a 22cv (meaning 'chevaux", so horsepower). In France you have to distinguish between "real" chevaux and taxable chevaux, as I am sure that you know. This would be taxeble cv.

[Allan L]

F12 Herbert Austin - Car 11 c1924 Austin 16

I think it may be an Austin 12/4, but I can't find a photo of one like it - all have sidelamps on the scuttle, not on the front wings.
Since I can't find the car, I can't give a different date, but the 12/4 was introduced in 1921 and I'd say this was before 1930.

Let someone else have a go now

Disagreing with Allan, I'll save this pair for him (it would be to complicated for me if I didn't) He only has to find the model.
So, this is an Austin, before 1930, with sidelamps on the front wings (I've seen others like that). Weren't there other models than the 12 and 16?

[Allan L]

Well of course there was the Austin 20, a fine and magnificent Vintage car. This just didn't look big enough about the engine room, but I suppose it must be. Let's say 1923.

This is more what I think of as a 20

[Ray B.]

That's it!  Austin 20 Limousine from the company who owns it. 1928 vintage. They don't seem to have changed much in all those years. I'm not a specialist in old Austins, but as they have several of them I suppose that they know what they are talking about. Here is the link (no, Otto and Ultra, this isn't giving away sources here: 6 Austins and that's all) http://www.weddingvintagecars.co.uk/cars.html

[Allemano]

F-14 is J. Frank Duryea who matches to car #1 the 1913 Stevens-Duryea Tourer.
The hint you unintentionally (?) gave by yourself...

Well, I measured the risks... Right.

[Allemano]

Never been able to solve cars from that era, but sometimes even a blind hen finds a grain of corn.

Not in France. This is a french car, remember. It's just for the sake of exactness.

'Torpédo'?

[Ray B.]

Torpédo it is. Thanks.

Just one left.

[Ray B.]

Today the count is, virtually:
Ehhxekt 9 points
Allan L 5 points
Impishgrin 3 points
Allemano 2 points

Which you haven't got on your account, guys, until someone gets to work and finds the 20th pair !

[Ray B.]

Which you haven't got on your account, guys, until someone gets to work and finds the 20th pair !

... which is Face 6 and Car 12. You still can't find what make this is? Here is another of the same.

[Paul Jaray]

Hugh Chalmers and a Chalmers Six 25hp from 1922-23

[Ray B.]

Thanks Paul, I knew I could count on you.
The thing I like best, besides a group puzzle by anyone well rounded up, is one of mine well rounded up.

The thing you'll like best is that I re-read my first post and I saw that each pair was getting you guys two points. So in fact the count goes like this...

Ehhxekt 18 points
Allan L 10 points
Impishgrin 6 points
Allemano 4 points
Paul Jaray 2 points

[ImpishGrin]

Thanks I don't want to sound too avaricious, but have you also icluded this?

Ehhxekt (gosh, man, I have to check each time so as not to mis-spell your name!) has the 2 points for the Martin pair, as he cleverly guessed my mistake. Nevertheless, I think that Impi... (same remark) and Allan L (no problem there) both deserve a point for having been mislead by me. Sorry.

[Ray B.]

No, I had not. This makes a lot of points for a single question, but since it had been a promise of mine...
Added.
