# United States Postage Meter Stamp Catalog/Sub-group PO-A – Stamps generated by commercial postage meters modified for use in post offices
#### Sub-group PO-A: Stamps generated by commercial postage meters modified for use in post offices

* he earliest uses of meters in post offices was experimental. Six Pitney Bowes "J" model series machines and five NCR meters (PO-A1, PO-A2) were trialed in high volume post offices for several months from late 1934 to 1936. The success of these tests led to an expansion. In 1936 a few thousand Pitney Bowes "JD" model series machines and several hundred National Postal Meter machines (PO-A3/-A4/-A5) were placed in post offices. The use of meters in post offices became widespread starting in 1940 with the purchase of tens of thousands of Pitney Bowes' new model "R" series machines (PO-A6). Nearly all post offices in the nation, save the smaller rural venues, received one.
* Most Post Office meter stamps are printed in red, but blue, green, orange, purple, and black stamps are occasionally found.
Type PO-FB6 in 2001 edition
PO-A1.1. Pitney Bowes "J", December 26, 1934.
    As Type FB2.2 but the meter number has P.O. prefix (except for variety a).
    Four machines were placed in five high volume post offices for trials:
       A. P.O.90059 CITY HALL ANNEX / NEW YORK, N.Y. (horizontal) [S]
       B. P.O.90060 NEW YORK, N.Y. (curved) [RRRR]
       C. P.O.90060 MAD. SQ. STA. / NEW YORK, N.Y. (horizontal) [S]
       D. P.O.90061 BROOKLYN, N.Y. (curved) [R]
       E. P.O.90062 WASHINGTON / D.C. (curved) [S]
    V/F: .00 : (range: .00½ to 9.99½)
       a. Without "P.O." prefix: 90016 MAD. SQ. STA. / NEW YORK, N.Y. (horizontal) [RRRR]
NOTES:
* Meter P.O.90060 ("NEW YORK / N.Y.", PO-A1.1B) was the first meter used in a U.S. post office. It was used for eleven days from December 20$^♦$ to December 31, 1934. It was replaced by meter 90016 (PO-A1.1a) on January 4, 1935 which was in us ten days only before being replaced by meter P.O.90060 with new town mark "MAD. SQ. STA. / NEW YORK, N.Y." on January 15, 1935. Both P.O.90060 with town mark "NEW YORK / N.Y." and 90016 with town mark "MAD. SQ. STA. / NEW YORK, N.Y." are extremely rare.
* First day of use for meter P.O.90061 was January 3, 1935.
* First day of use for meter P.O.90062 was March 8, 1935.
* Examples are known with slogan commemorating the silver jubilee of parcel post in 1938.
♦ Although the earliest date known on a postally used stamp is December 26, 1934 a zero cent proof of P.O.90060 ("NEW YORK / N.Y.") exists dated December 20th. The earlier date is probably closer to the actual first day of use (which remains unknown) since the machine was probably installed to see if it would speed the franking of Christmas parcels.
