Well, this took a lot longer to find than it should, but neither of the web pages where this picture can be found contains the word "universal" in its text, so that was completely useless as a search term.
And there is no supporting information either, but there is a high-resolution picture on the US Library of Congress site which at least allows you to read the notice fixed on the car.
So according to that, this is a Ford with Universal body by R. Mc. Reynolds and Son, of 1423 to 1427 L St. N.W.
I wasn't sure what the address was meant to be at first, but there is a road called "L Street Northwest" in Washington DC, which has street numbers that go higher than 1427, so that might be it, but I'm not completely sure.
