*    This list has taken several years to compile and while the data were valid at the time of entry, changes in location and ownership may
       have occurred since that time. Additionally, I know of a number of machines whose owners have asked to be excluded from this list - if
       you are looking for information on a particular serial number or Enigma variant which is not listed please contact me by email.
⁺    The Army/GAF machine is the 'standard', 3-wheel version [Modell I],  used by the German Army and Air Force.
^@    It is known from contemporary records that naval Enigmas in the range M501-M1821 were designated  M1 or M2 but the changeover
       point from M1 to M2 is unclear. Some M2 machines listed here may therefore be M1. The first M3 carries the serial number M1822
       while the first of the M4 series is M2802.
#     'TIRPITZ' was the code name assigned by Bletchley Park to Enigma T - a modified Commercial Enigma K supplied by Germany
        to the Japanese navy. TIRPITZ has eight wheels, each of which has five turnover notches.

  ¹  wheels are from two different Navy machines - M1332 [VI, VI],   M1322[VIII]:UKW is A16991
  ²  wheels are from A18131 [III, V] and A16801 [V]
  ³  wheels are from M1332 [II, IV, V]
  ⁴  wheels are from M3887 [I, III, V]; Gamma from M5520
  ⁵  'The German Enigma Cipher Machine'; Collectors' Video Services; ©1990 Joe Shray
  ⁶ wheels are from K812
  ⁷ reported - not confirmed
  ⁸ wheels from two different Navy machines: M983 [V & VI],  M867[VII]: Courtesy Maj. R. Pickard (Retd.)
  ⁹ wheels are from A19771 [III & V] and A19811[II]
¹⁰ removed from BP exhibit in mid 1999 and returned to GCHQ. M3097 was later presented [September 16, 2000]
     by HRH the Duke of York to Mr. Jerzy Buzek, Prime Minister of Poland
¹¹ replaces M3097 in BP exhibit
¹² wheels are from M15700 [II, VI] and M16253 [I]; Beta from M16532; 'Thin' C reflector M5620. 
     M15700 [VI] is non-standard in that, while it contains the wired core of M15700 [VI], it has the
     single-notch ring of an unidentified Wheel III [notch is at ‘D’] - clearly engraved with the number ‘3’.
     Obviously, any Walzenlage which includes this wheel will not provide an output of meaningful
     ciphertext or plaintext.
¹³ one of six machines built in France in 1940 by the Polish team in exile: it has no s/n but all wheels,
     including the UKW, are engraved 'A' - this machine is, regrettably, not in working condition: [for a
     photograph see 'The Enigma War'; Jozef Garlinski; Scribners; 1980]
¹⁴ wheels are A02188 [I], A01512 [II], A01834 [III], 10731 [IV] and 18840 [V]
¹⁵ wheels are from A00908, A01400, 0676??
¹⁶ wheels are M8264 [ I, II, V], Gamma from M6927, 'Thin' C reflector M18345. Collection also includes an
     unidentified wheel - metal engraved A-Z - with no serial number and non-standard wiring and two Army/GAF
     wheels: A5514 [I, III]

²⁰ wheels are A7403 [II], A13530 [IV], A10224 [V], UKW = D [A11391]
²¹ described in detail, with photographs, in: 'G-312: An Abwehr Enigma', Hamer, D.H., Cryptologia 24(1), January 2000
²² K765 is featured as an illustration in 'Station X' by Michael Smith [Channel 4 Books, 1998] and wrongly captioned
      in early  printings as a navy M4
²³ the 'Norway' Enigma is a standard Army/GAF machine, modified for use, post-war, by the Norwegian Special Branch
     [Overvaakingspolitiet] by rewiring of all wheels except the ETW. The recent discovery that A13526/jla/41 has the
     modified wiring suggests that may be other machines listed here as 'Army/GAF' which are in fact  'Norway' Enigmas.
²⁴ wheels are A5760 [I], A16207 [II], A4229 [III], A5846 [IV], A1283 [V]: UKW B

⁷⁰ although, according to Swiss records, K470 was included in the second batch of machines delivered
     on 1 July 1939 it does not appear to have been modified and remains in its original Commercial configuration
⁷¹ There is a third Enigma at IWM whose serial number is not currently available.
⁷² this collection also contains an 'Uhr' box.
⁷³ M897 is accompanied by its Begleitbuch which shows it to have been on board the pocket battleship Lützow
     [formerly Deutschland] during that ship's service from 1934 until its surrender in 1945. Wheels are all M897
     [I, II, III]; UKW = 'B'
⁷⁴ wheels are from M983 [I, II, III]; UKW = 'C' [M1146]
⁷⁵ wheels are from A2606 [I, II, V]: the collection also contains Navy wheel M8573 [IV].
⁷⁶ wheels are all from A10894 [I, II, V]; UKW = 'B'.
⁷⁷ M2946 was recovered from the wreck of U-85 on 3 July 2001. At the same time the entire scrambler assembly of M3131
     was recovered. These artefacts are in a remarkably good state of preservation. With this double recovery all of the wheels
     but one from both M2946 and M3131 have been recovered. On 22 August 2002 the rest of M3131 was recovered.  For
     details see U-85 pages. 
⁷⁸ Though carrying a Commercial serial number K932 is a bit of a 'hybrid' - wheels are from three different Army/GAF machines:
    A19761 [I], A19811 [IV], A14033 [V]:  UKW is 11018 and its index ring carries 1-26 markings.
⁷⁹ wheels are A01174 [I], A02188 [II], A00986 [III], A20719 [IV], A 02192 [V]; UKW='B' [A2229]: spare wheels in oak box.
⁸⁰ this machine is fabricated from metal of the same beige color as A20531 [see note 44].
⁸¹ wheels and UKW are all marked B207 [I, II, III] but the wiring of  all wheels except ETW is non-standard and the UKW is
     otherwise unmarked. The index markings on all wheels are in red.
⁸² wheels are A12672 [IV, V] and A468 [V]; UKW = 'B' [A11769].
⁸³ cover is of beige metal construction - similar to A20531. Wheels are all A20567 [I-V]; information courtesy Dr. Mark Baldwin.
⁸⁴ all three GCHQ machines examined by the author on 18 November 2004.
