Solved: Enigma variations (Prewar cyclecar edition)

[Wendax]

Another batch of cars unknown to me, probably all German or Austrian again. #5 seems to be a little bit larger than the other ones. Have fun!

One point each for correct identifications, which have to be proven.
Points will be awarded immediately when earned.

A tough one!

Prewar cyclecar enigma 2.- I knew I'd seen this one:
Here a first of the fabulous collection of unidentified cars from Berlin based car historian Thomas Ulrich who visited us at the Paris Retromobile. Check this young fellow taking his first practice in a sturdy three wheeler of unknown origin. As the photo is German, that is the first country of manufacture to think of. On sheer visual judgement we presume it has a rear mounted aircooled engine. The vintage is a gamble, but we think early twenties. You may know and we are looking out for your opinion.

It's not an answer, there are two guesses:
Update IV by Thomas Ulrich: It's certainly no Diabolo. They where quite similar to the Morgans. I think it's a Mollmobile, even if they had normally four wheels, but otherwise they are quite similar.
Update III by editor Rutger Booy: I have my doubts about this car being a Diabolo. They were based on the Morgan and had a V-twin front-mounted Motosachoche engine. This car has clearly a mid-mounted kick-start engine.
Update II: best headline by Mark Nugent of Nugent Coachbuilding
Update by Wim van Rooijen: "I think that it is a German "Diabolo" produced between 1922-1927. Diabolo Kleinauto A.G Bruchsal"

I know that site. It is definitely not a Diabolo as you can see by comparing it with the Diabolo pictures at AutoPuzzles: http://www.autopuzzles.com/forum/index.php?topic=16700.0
I don't know any mention of a Mollmobil threewheeler. The Mollmobil is covered quite well in German car literature, and they all write about a fourwheeler only.

The Mollmobil was a tandem seater, which this one isn't. The proportions are different, too. Compare http://www.autopuzzles.com/forum/index.php?topic=4856.0

I was able to identify enigma #6 by looking through old magazines. It is definitely not a Mollmobil.

I decided to separate #6 from the ones still unknown to me.
It can be found here now: http://www.autopuzzles.com/forum/index.php?topic=21966.new#new

I found a 1925 ad for the Borcharding which I will post later today. I think car no4 is a Borcharding

[Wendax]

I'm looking forward to it.

Thank you very much for sharing the Borcharding drawing.

Having looked through my books I found that the Borcharding was an unmodified continuation of the Mollmobil. (Before that they built a three-wheeler I don't know a picture of.) I have attached a Mollmobil ad by Borcharding with the same drawing I happened to find right now by Google search.

I don't think #4 is a Borcharding or Mollmobil, because a characteristic feature of the Mollmobil was the absence of an Ackermann steering. It had a primitive pivot steering. Puzzle picture #4 shows a connection between the front axle near the wheels and the rest of the car. This rules out a pivot steering. Further on it seems to me that the axle is located more up front than the one of the Mollmobil.

Keep your eyes open. Some day we will find out...

Is #2 a circa 1923 Mops?

Is #2 a circa 1923 Mops?

I don't know what it is, but I know that it is not a Mops, because that one looked different: http://www.autopuzzles.com/forum/index.php?topic=13656.0

One year without another guess 

Open for all now.

[Wendax]

I added a new #6 which looks quite spectacular. Any ideas, guys? I don't know anything about it.

[Wendax]

#4 is a repost. I'm sure that it is another Baja Cyclecar: http://www.autopuzzles.com/forum/index.php?topic=21966

Two well-earned points for opening my eyes.

Similar, but not the same I think.
