Something very fishy about that.
Seems to me the USA was not at war in 1941 so they mail service could probably have bought a truck.
Even if the USA was at war they will would have provided the USPS with a truck.
And from the looks of things.
I'm not even sure that could turn
There is also something wrong with the front steel spoke but rear wooden spoke rims.
Not sure why but it just does not look right.
I think what you have there is someone's fraken car from who knows when.
Ah one more point.
As a collector of things....
I notice the USA govermernt realy liked to put their name on things back in those days.
prime example are the USFS ( forest service ) lanterns and tools.
Its hard to fake that stuff when it was so clearly marked and documented.
This thing????????
