From Shorpy - note the long wheelbase Plymouth

[nzcarnerd]

From The Standard Catalog I see Plymouth built a couple of thousand of these.

 

Note also chains on the rear tyres. I guess they could have put them on the front as well if it was icy enough?

Those 7 seat cars as Plymouth,Dodge and Chevrolet was common here in Sweden  as Taxi cars from late 1930s up to early 1950s.

Most of the long wheelbase, seven passenger sedans of low and medium-price makes were used in taxi or livery operations.  As such, they generally had the wheels run off them, accumulated high miles and since there was little demand for them after that service, were junked.  That's why, in addition to the relatively lower production numbers initially, their survival rate is so low.
