MODEL Z: A NUMBERS-ONLY ENIGMA VERSION
Cryptologia, Apr 2004 by Arturo Quirantes[The Figures referenced in the original article are not available at this time]
ABSTRACT: A review of pre-WWII documents in the Spanish Foreign Affairs Ministry has discovered a hitherto unknown Enigma modification, called "Model Z", capable of encrypting numbers only. This model seems to be unknown to the Enigma community. The few known details concerning Enigma Z are outlined here.
In November 10, 1931, the Spanish Ministry of State (Foreign Affairs) made a request to its Berlin embassy to report on cipher machines used in Germany. Within a week, the Chiffriermaschinen Aktiengessellschaft answered the embassy's queries with an offer for three types of machines [1]. The first, labeled "ENIGMA Model A 27", seems to be the standard, commercial model.
