Productmobiles...almost solved!

... and advertising cars.

Eight cars adorned with different gimmicks, or in form of gizmos. What they advertise is usually obvious. But what I am interested in is what chassis or underpinnings are hidden under. Give us the make, possibly model and year.
Each picture is worth one point, except the last two, for which I have no information: those, if identified with documented evidence, will be worth two.

1921 Dodge - 75america

I hope it wasn't too hard guessing this, Paul.
I expect better from you.

#5 Daimler Worthington 1923

Fine... I just knew it was a Daimler.

#3: is this wienermobile based on a 1952 dodge chassis?

Dodge is correct, 1952 is not the year I have.
So, what kind of Dodge, and what year (you're close). Locked for you until your next answer.

[Ray B.]

#1: 1921 Dodge

Exact.

[Ray B.]

#6: 1936 Studebaker

Correct, but what model of Studebaker? Locked for you til your next answer.

[Ray B.]

#4: 1932 White

Exact. You're sweeping this one clean!

[75america]

#6: 1936 Studebaker

Correct, but what model of Studebaker? Locked for you til your next answer.

I'm not an expert in American cars and I can only find that it was based on a 'Studebaker Coupé'.  If I'm correct, in 1936 Studebaker only had the 'Dictator' and 'President' in their line-up...but both of them were available with a coupé body...

[Ray B.]

It's said "possibly model and year". My source (which is not on the internet) gives the model. I'd like you to find it, but it's not mandatory. The difference between both will be the wheelbase, of course.

#3: is this wienermobile based on a 1952 dodge chassis?

Dodge is correct, 1952 is not the year I have.
So, what kind of Dodge, and what year (you're close). Locked for you until your next answer.

Also for this one, I cant find more information. 
This model of the wienermobile was made in the period 1950-1953.  This one looks a little bit older than the better known 1952 one, so I guess 1951...

[Ray B.]

I won't be a nitpicker regarding the year, but  what kind of Dodge chassis? It is on the internet.
Still locked for 75america.

#8 is styled (if you can call it styling) like a Hanomag Kommisbrot. So is it a Hanomag?

[Ray B.]

If you read the first post, you'll see that I don't know. But if it was one, it would be a giant Kommisbrot.

[João]

Numer #2 It´s a 1928 Studebaker?

[Ray B.]

Good enough! (1929)
