Thanks for the comments. Very interesting info.
Here are two more Poughkeepsie, NY precancels. I think they are either a 424 or 485 but in both read down and read up varieties (the latter looks to be a double or triple strike).
In both examples, it looks to be 13 mm between bars; 2 mm below top bar to city name and 2 mm between city and state name.

Any help to confirm which varieties are shown would be most helpful.
Thanks.
