A fragment of an Enigma Schreibmax, a small printer which attached to a naval M4 Enigma machine to print the encoded message. The Schreibmax replaced the need to take down the letters lighting up on the lamp board by hand. This example is in a fairly poor condition, but is nevertheless an extremely rare accessory. This fragment, which was discovered with the remains of an M4 Enigma machine, forms the left part of the base plate. On the top face of the fragment is a label that reads, "Bei gedrückter Taste des Schlüssels M Walzen nicht bewegen", although this is illegible due to corrosion.
