SOLVED: si_751 - Deiters - Typ Göttingen - Henschel-Imbert - by Wegmann - 1935

[marmer]

1933 bus built by Triebwagen und Waggonfabrik Wismar AG, Seestadt Wismar and the Railway Transport Company (EVA) based on Dr. Deiters' system with a completely electrically welded body made of rust-proof steel and a modified Henschel engine with an Imbert wood gas generator.  Another source shows a similar bus credited to Henschel with a body by Wegmann, 1936.

You're right, it's a design by Dr Josef Deiters from 1933 with a wood gas drive based on a Henschel engine. Locked for you to determine body builder and model designation. There are three attempts.

[marmer]

Body builder: Credé?

[sichel]

No.

[marmer]

Body builder: Wegmann?

Model designation?  Do you mean a Henschel model designation for the chassis?  If so, 5 D 1?

[sichel]

Yes, the coachbuilder was Wegmann.
The model destignation was a name.

[marmer]

Built 1935 (some sources say 1936 but more say 1935).  This is the first of several examples built for Göttingen.  The Göttingen Omnibusfreunde gives it the number IS-20376; there is no "Wagen" number known.  Are you looking for a different name?

[sichel]

1935 is correct. This type was named after a town.

[marmer]

Rostocker?

[sichel]

No, one more attempt.

[marmer]

Dieters-Wismar?

[sichel]

no. Unlocked

[marmer]

Göttingen?

What lasts a long time will finally be good. The puzzle bus is a Deiters, Göttingen type, with a Henschel-Imbert wood carburettor engine, built by Wegmann in 1935.
Here is your next point.

[marmer]

Interesting.  I actually found several mentions of these buses in German-language sources, including a couple from Göttingen, plus a couple of mentions in well-known English sources.  However, I never found mention of them being called "Typ Göttingen" or anything like that.

Prof. Dr. Ing. Josef Deiters is another mystery.  He seemed to hold patents for vehicle seating and construction, and his design for self-supporting bus chassis incorporating the wood-gas generator seems to be his biggest claim to fame.  Apparently he designed similar buses for Stille (a four-axle beast) and VOMAG (several hundred were apparently built by Harmening.). He was appointed to a fairly important transportation committee in 1939 but died of pneumonia in Berlin in 1940.

The Henschel wood gas buses bodied by Waggonfabrik Wismar for Rostock looked very much the same (except for the radiator). Perhaps the seat arrangement was different than that in the Göttingen buses, or Typ Göttingen was just a Wegmann name (like Autenrieth named their bodies after the town of the first customer of that body type).

[marmer]

Yes, I saw a Göttingen source that pointed out the "modernized" (their word) bonnet for the later buses.  Apparently there were a few used in Göttingen in the later 1930s.

[sichel]

Yes, the Wegmann type 'Göttingen' differed from the Rostock Eva versions from Wismar by the radiator grille and the bumper.
Prof Dr Deiters acquired patents for self-supporting lightweight bodies, among other things. When the supply of aluminium and steel became a problem in the mid-1930s, he developed the material 'Delignit', a plywood glued with Kaulit, for a raw material-saving lightweight construction method. There are reports of its successful use right into the post-war period.
The first Deiters lightweight construction project was the aforementioned four-axle vehicle. That would have been an interesting AP project, but it has now been burnt...

[marmer]

That would have been an interesting AP project, but it has now been burnt...

Sorry, for what it's worth I would have recognized that immediately from all the searching I did for this puzzle!

It's not like the world is going to end.
