This is the only military record book I have seen, and therefore have no other basis for comparison. It was issued at the end of 1904, when this cavalryman completed his active duty hitch and joined a reserve unit in the city of Szeged. He emigrated to America in 1912 and brought this military record book with him.

Format: This example is a staple and tape-bound booklet with a cloth-covered cardboard cover. In total, it contains 40 pages, most of which are pages for stamps and signatures (such as page 9 which is shown) or they simply are a recitation of regulations. Only the pages used for recording individual-specific information are shown here. Attached to the booklet by clips were two identical cards showing the basic identifying information found on the Cover Page; the purpose of these cards is unknown.

Content of Booklet.
Cover Page.
- The title Népfölkelési igazolványi könyv means something like "Militia Pass Book."
- Above the title: "Magyar royal militia district 14 of Szeged" -- below left (almost illegible) is f. sz. 16 meaning "sequential number 16" -- then at the right the owner's military ID number: 1891/421. for further information about military ID numbers and a probable discrepancy in this record.
- Below the title: the name (Heszlényi Gyula; a description of his previous service -- in this case "he was a cavalryman in the Imperial and Royal 1st Cavalry Regiment" (volt huszár a cs. és kir. 1 huszár ezredben); and below is his birth year, 1872.
Page 1. Most of this page repeats the information on the cover page. At the bottom are two boxes. The first is intended to specify the depot where a new militia member is to report to be inducted and receive his equipment; this does not apply to this long-time cavalryman. The second box gives the period during which he is required to be part of the militia (ie reserve unit) in his place of residence. Here the period specified is "from 1905 up to and including 1913."
Page 3. This is a summary of his military service to date, I will translate rather literally so the context should be obvious from the printed and manuscript entries: Julius Heszlényi was born ("született") in the year 1872, in the town of Budapest, in the capital district of PPSK county of Hungary, into the Roman Catholic confession and served ("szolgált") in the Imperial and Royal 1st Huszár Regiment 10 years, 1 month, and 10 days, and in the 4th Magyar Royal Volunteer Honvéd Cavalry Regiment for two years, for a total of 12 years, 1 month, and 10 days.
Pages 4-5. Continue using a "fill-in the blanks" format with details of a military career. In this example, most of page 4 is not applicable, and most of page 5 is crossed-out.
Pages 6-7. Beginning with the last line of page 5, the dialog moves on to the reserve obligations of the man. Again translating rather literally, it reads:
This cavalryman owes (tartozik) obligatory (köteles) service to the militia, in the 1st class (1-sö osztályábna basically "active reserve") until 31 December 1908, and in the 2nd class (2-dik osztályábna basically "inactive reserve") to be concluded (végéig) in the year 1913.
Page 7 repeats much of the information from the cover page and establishes the place of legal domicile (illetöség) and current whereabouts (tartózkodási hely). For this man, both are within the city (városi) of Szeged, in Csongrád county, Hungary.
Pages 8-9. Page 8 identifies again his active service (Ténylegesen szolgált) unit.
Page 9 (and subsequent blank pages) provide places for commanders to stamp and sign the record. In 1905 and 1906, he apparently lived in Szeged where this military record book was issued, and therefore was not required to have it stamped. In 1907 and 1908 he lived in Técsö in Máramaros county in extreme northeast Hungary. Here his record book was stamped annually by the local militia commander.
