Solved: Back To The Egg - The Brütsch puzzle

Egg 24: Brütsch V2, 1956-58

Sorry, I missed that one. You are right that this is the Brütsch V2 (Volkszweisitzer), a kind of further minituarized Pfeil. I have it built from 1957 to 1958.

Egg 15 : Brütsch Zwerg Zweisitzer from 1955 ?

I'll accept that answer, although the 24 hours weren't completely over, but they are now. 
Yes, it is the Brütsch Zwerg Zweisitzer with a beautiful acrylic glass hardtop, probably a one-off. It would be interesting to see how it opened (forward, backwards or sideways).

You think in the right direction, but in the wrong language. Think German! 

ok, you mean K (Kabriolet)?

Is #14 the rejected Böbel/Laupheim prototype?

Egg 29 BRÜTSCH ZWERG II FROM 1956 only 5 units were made

Yes, Egg 26 is the Brütsch K 400, bodied by Wendler. We had it before: http://www.autopuzzles.com/forum/index.php?topic=18382.0#top

[Wendax]

Is #14 the rejected Böbel/Laupheim prototype?

Yes, it is. It had a designation, too. I'm sure you will find it.

Egg 29 BRÜTSCH ZWERG II FROM 1956 only 5 units were made

Yes, it is the second version of the Zwerg without flared headlights.

[Allemano]

Is #14 the rejected Böbel/Laupheim prototype?

Yes, it is. It had a designation, too. I'm sure you will find it. 

I only could find that it was based on a bigger chassis and on a 300 cc engine. Brütsch 300, then?

I am looking for a single letter again (and Mr. Thyssen-... doesn't mention it).

egg#26: Brutsch Egon ?

[Wendax]

egg#26: Brutsch Egon ?

No, Egg #26 is already solved, and Egon was Brütsch's first name.
No 24 hour lock for this guess

I think Egg 37 is a Victoria 250, a later development of the four-wheeled Spatz made by the Victoria motorcycle company, with a similar body but with a curved one-piece windscreen, Victoria's own 250 cc engine and an electrically operated gearbox.

Yes, Victoria took over the BAG Spatz production and modified the Spatz by enlarging the engine to 250 cc and altering the body.

Egg #36 is the French version of the Rollera, which I think was built by Société Air Tourist as per the Avolette

Egg 10 BELCAR swiss version of the first BRÜTSCH SPATZ threewheeler. That picture appears in a brochure of the builder (A.Grünhut & Co.) without mention to a special name to this model with doors.
