The only stamp in Group D to have curved top and bottom frame lines in the frank.
A single postage meter was imported on trial from London by Pitney Bowes. It was used for a short time in 1927 by American Telephone & Telegraph Co., New York. It is believed to have been a multi-denomination "Midget" model with either three or five postage values although only the two cent stamp is known postally used.
Two examples of a five cent stamp are known. They differ from the two cent stamp in having a Roman numeral month. They are considered essays although it has been speculated that because five cents was the basic international postal rate in 1927 that that value was fitted with the Roman numeral month because it was often used in Europe. The five cent stamp also does not show the mailing permit number which would be meaningless on overseas mail. Neither of the two five cent stamps are on cover.
DA1. "Midget" model (LV-3), 1927. [RRRR]
Frank with vertical sides and curved top and bottom.
"METER NO.145" in bottom panel.
One machine was used on a trial basis for a short time only.
Only the 2¢ denomination is confirmed as used on actual mail, but the machine could print a 5¢ value and another unknown value, probably 1¢.
Value: 2¢ One full cover and one cover front known
Value: 5¢ One undaddressed cover and one cut-out known
NOTE: The 2¢ value has town mark with "PERMIT 14" at bottom. The 5¢ value has different town mark and Roman month in the date.
Sub-group DB – Pitney Bowes (The Postage Meter Company)edit
After nearly a decade of producing the motor-driven Model M meter that produced the Sub-group CA stamps Pitney Bowes was ready to market a less costly hand-cranked model for smaller mailers. This meter was the Model H and its variants H5, H3, HS, HT, HX, and HE. The "H" series meters produced most of the stamps in Sub-group DB.
To promote the new meter model Pitney Bowes mailed out tens of thousands of announcements to businesses throughout the country from 1929 to 1932. Because of the high volume it was impractical to use the hand-cranked H meters, and the company used the motor-driven Model M for this purpose. Since these mailings were promotions for the new Model H, the seven Model M meters selected for the mailing campaign were fitted with the new DB style die in place of the old oval (CA) die. The stamps from these hybrid meters are cataloged here as Types DB1.2 through DB1.5.
Type DB stamps always have a double circle town mark, normally 24mm in diameter, or no town mark when used on registered mail.
All Type DB stamps, except for DB1.2, have single line date.
Some meters were fitted with a special attachment that produced impressions on adhesive tapes. (See "Meter safety paper tapes" (paper Types 1 and 2) in the Table of Contents.) Spacing between the town mark and frank is 27 mm on stamps printed on envelopes and post cards but only 8 to 10 mm on stamps applied to safety paper tape.
Sub-groups DB and DC are similar in appearance. Please read the description for Sub-group DC for points of identification.
Earliest known date of use, January 16, 1929.

DB3. Model "HS (FV-1). [RRRR]
As Types DB1.1 and DB2.1 but "P.B. METER" precedes the meter number.
Similar in appearance to Sub-group DB, National Postal Meter (DC) stamps are most easily identified by the wording in the bottom of the frank. The earlier stamps, Types DC1.1 through DC1.3 are inscribed "METER NO." as do most DB types, but the meter numbers are usually 3 and never more than 4 digits while all DB stamps have 5-digit meter numbers.
The value figures in the circles at the sides of the frank are generally larger than with the DB stamps, and the triangular ornaments below the central oval extend farther into the center of the frank.
Date figures are 2- or 3-line.
Town marks are usually double circle (DC) but often found with broken inner circle (BIC). Two machines are known with single circle (SC) town mark.
A special attachment for printing stamps on adhesive tapes was available. Stamps on tape usually have much narrower spacing than those applied directly to the mail piece.
Meter models: "A" (4 values, hand feed), "B" (4 values, auto feed), and "M" (single value)

Sub-group DD – International Postal Supply Companyedit
Similar in appearance to Sub-groups DB and DC, the stamps of Sub-group DD are distinguished by the relatively wide spacing between the inner and outer circles of the town mark. The lettering within the town mark is generally taller and narrower than with DB and DC, and the town name usually, but not always, is followed by a comma.
The spacing between the town mark and the frank can vary greatly.
The date is always a single line.
Meter model: "4" (5 values) fitting on mailing machine models 2, 3, and 5.

NOTE: Type DD stamps which include PERMIT No 8,P-8or other variations in the town mark are philatelic fabrications produced by Henry Meisel. Meisel was the founder of the American Metered Postage Society and publisher of the AMPS Bulletin which was produced from the 1940s into the 1960s. Other unauthorized Meisel creations: I.P.S. No. replacing "METER NO." at the bottom of the frank, meters 5504 and 5652 with dots or arcs added at the sides of the TM.
The stamps in Sub-groups DA through DD were from fixed value (FV) machines, most of which were capable of printing more than one frank die, each die showing a different postage value. The meters producing Sub-group DE stamps had only a single frank die, but it contained a gap or hole in the center into which a small postage value die could be inserted. Because postage value dies can be much smaller than dies for a complete frank, the meters could accommodate a wider range of postage values. The meters that produced Sub-group DE stamps could all print ten different postage denominations.
Meter model: "HX" (1¢ to 20¢) and "HT" (1¢ to $1), limited value machines with ten postage values (LV-10)

Meter numbers assigned to Types DE1, DE2, and DE3 are found occasionally on different DE types. When machines were turned in for repair or reconditioning the print-head dies were not always re-fitted to the same meter.
Meters 61000–62999, 80000–81999 and 89000–89999 were allocated to the Model HT. Meters 63000–79999 and 82000–88999 were allocated to the Model HX. Not all numbers were used.
Numbers 82400 to 84999 were assigned to meters used in Canada. Forty-one numbers between 63698 and 88769 were assigned to meters used in The Philippines.
DE1. Models "HT" and "HX" (LV-10).
Meter number with "METER NO." prefix at bottom of frank.

DE3. Models "HT" and "HX" (LV-10).
As Type DE1B but meter number with "P.B. METER" prefix.
Meter numbers 61000-61100s, 63000-67000s, 70000-79999, 86293-87903, 87905-88999, 89123-89999, plus a few numbers previously used with Type DE1 and DE2 dies.
The franks are very similar in appearance to those of Sub-group DE but are slightly larger (23½ mm square), most easily identified in the taller letters in "U.S. POSTAGE". Type DF3.5 is an exception which apparently utilized leftover DE dies.
All DF town marks are larger than used with DE stamps, 26-27 mm in diameter compared to 24-25 mm, and all have multi-line date (or no date) unless only the year is shown (occasionally used on bulk mail that was not allowed to show the date).

Model CV and Model CVS were both marketed – they were both LV-6, but used different-sized slogans.
Meter numbers were allocated as follows: 55000–56424 for the Model CV, 57000–59999 for the Model CVS.
The 54000 series numbers may have been issued fairly late, possibly after 1944.
DF1. “MS” and “CS” (FV-1).
Meter number with "METER NO." prefix.
Narrow (5 mm) spacing between town mark and frank.

NOTES:
Meter number 50000 was assigned to WOR radio station of New York. It was deliberately requested because the station was proud of its 50000 watts broadcasting power.
Meter number 55539 with cut-outs in the sides of the town mark rings is a philatelic fabrication prepared by Henry Meisel. (See the NOTE following Type DD2.)
