Diesel-engine is missing. Who was the manufactorer of the chassis? Who built the body and when? Where was it used? One point for four answers.

It was a Stadt Heilbronn trolleybus which ran until 1960, when they were replaced by diesel buses. Some were sold to the town of Braga in Portugal.
They were bodied by Heilbronn companies Wankmiller and Drögmöller in 1951 to 1955, but I haven't been able to find out what the chassis was yet..

Locked for You till Tuesday. Than I'll be back from a short business trip. Please decide also, who was the coachbuilder and have a look at the front-wheels...

Information is very thin on the ground.
I think this particular one was by Karosserie Wankmiller, but the chassis is purely guesswork. Henschel?

Yes, it is Henschel, but please more details. Coachbuilder is a 50:50-choice  ;)

In that case it must be Gotthard Drögmöller?
Title: Re: si_029

Yes, it is Drögmöller. But I miss the details of the bus.

Oh, I thought I'd answered the four questions ("Who was the manufactorer of the chassis? Who built the body and when? Where was it used? One point for four answers"):

It's a Stadt Heilbronn trolleybus bodied by Gotthard Drögmöller on a Henschel chassis in 1951. It remained in service only until 1960 when some of them were sold for operation in Braga, Portugal.

Since you specially said to look at the front wheels maybe that's what you're referring to.
The front wheels are also double, like at the rear, which is very unusual but I don't know the reason. Surely not FWD or AWD?
Perhaps it's something to do with the fact the trolleybuses could also tow a passenger trailer, and there were 3 trailers on the fleet along with 7 Henschel buses. But the law was changed in the early 1960s and they would no longer be allowed to tow a trailer.

Sorry Carnut, my mistake. Genrally I ask for manufactorer and type (Henschel II-6500), but in this case, I forgot it. So, your answer is complete and you have earned the point.

For double tyres: there are two explanations for this.

First: For trolleybusses type II (two axles, up to 90 passengers), tyres in the dimension 12.00-20 where needed, but because of the war preparations not available in sufficient quantity. So, double tyres 9.00-20 were used by Henschel as a substitute. This is a trademark for first generation Henschel-trolleybuses

Second: Through the smaller tyres the entrance height could be lowered, an advantage for the fast flow of passengers.

Thanks Sichel.
Just to add a little more information, the fleet numbers of the Henschel buses were 201/206 and the chassis numbers were 25230/5.

Regarding the double tyres, I did wonder if they really were double (I know it says they are on one of the Heilbronn historical sites) as it's not really possible to make them out clearly and it would make the buses very heavy to steer.  But your explanation is logical and I'm sure you're right.

I studied pictures of the buses after they were sold to Braga but I still couldn't make it out if they really were double at the front!:

Carnut, thank you for this background-informations.
You are right with the problem of steering forces. And so Henschel used pneumatic power steering.
