Peter's right, and I apologize to you all because my request was horribly unclear.
They are indeed Chicago, Akron and Cincinnati, but I was talking about the font. These coil precancels with vertical bars and the city/state running up and down the stamp vertically form a subgroup known as "city coils" (there are some horizontal ones, too, but obviously the vertical ones stand out as being different from most other precancels, which tend to be horizontal anyway).
In the Local (Town and Type) catalog, there is a page that shows the various types of precancel that go on city coils -- there are 15 slightly different vertical types (based on size of lettering, font, distance between the vertical lines, etc.) BUT none of them has a font as tiny as this or lines that are so close together.
I also checked under each town individually and did not find another (not city coil) type of precancel that these could be.
So I am wondering if anyone knows how they came about and whether they are officially "precancels" or something else -- post-cancel, box cancel, etc etc
Sorry again and here is a scan of the catalog page that lists all the types of city coil precancels, so you can see what I'm talking about:
