Question About 1975 Machine Cancel Cds On US Stamp

I believe it reads:

Postal Service, NE
PM
Aug 27
1975

Why not a town name? I know there is no town in Nebraska called Postal Service.

There are a few "indecipherable" letters before "POSTAL SERVICE". Unfortunately the last couple of digits of the zip code are also indecipherable.

Found another one, "Postal Service, OH". 1973. Larger CDS.

Adams, NE Pitney Bowles model B110

OK, I guess it could be "U.S. POSTAL SERVICE". I found a few postmarks like that, but from an earlier era on US government mail. But I don't know if that is related.

For Ohio these were Pitney Bowles and were used in Bowling Green, Cuyahuga Falls, Hamilton and Cincinnati.

Your cancel is Cincinnati (453)

The 3 digits following NE represent a district sorting center, "680". Included in 680 is Boys' Town:

BOYSTOWN POST OFFICE - 2 BOYSTOWN 68010
139 S 144TH ST BOYSTOWN POST OFFICE - 3 BOYSTOWN 68010
139 S 144TH ST BOYSTOWN POST OFFICE - 4 BOYSTOWN 68010
139 S 144TH ST BOYSTOWN STATION LOBBY - 1 BOYSTOWN 68010
139 S 144TH ST BOYSTOWN STATION LOBBY - 2 BOYSTOWN 68010
139 S 144TH ST BOYSTOWN STATION LOBBY - 3 BOYSTOWN 68010
139 S 144TH ST BOYSTOWN STATION LOBBY - 4 BOYSTOWN 68010
139 S 144TH ST APC UNIT IN BOYSTOWN LOBBY AREA - 5 BOYSTOWN 68010
139 S 144TH ST 139 S 144TH ST - BOYSTOWN STA. BOYSTOWN 68010

A nice find from St. Paul, MN
