*    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.
#    '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.
##  'Spanish Enigma' - rewired variant based on the Commercial machine and sold to Spain during the Spanish Civil War.

  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 but not confirmed: A12593 REPORTED AS STOLEN MARCH 2016
  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]

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

⁶³ wheels are M15653 [I, II, V]. There is no UKW or Zusatzwalze - instead Wheel IV is installed in the left-hand position
    and has been modified to act as a reflector by crudely soldering wired links across the plate contacts. Information

⁷⁰ although, according to Swiss records, K470 was included in the second batch of machines delivered to
     Switzerland on 1 July 1939 it does not appear to have been modified and remains in its original 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'

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.

⁹⁰ 'Norway' modified wiring: wheels are A3386 [I], A16411 [II], A13529 [III]: UKW = 'B' [A12760].
⁹¹ wheels I, II, and III are from G130: UKW is original. G128, G213 and G??? were used post-WW2 by the Royal Dutch Navy.
⁹² wheels are marked G128 [I, II, III].
⁹³ wheels are all A13852 [II, III, IV and UKWB].
⁹⁴ probably A19615/jla/44 but data plate is missing: similar features to A19723, A20531/jla/44 and A20662/jla/44 - see notes
     #44, #80. When this machine was first brought to my attention the installed wheels were from three different navy machines,
     M2990 [III], M16687 [II], M18198 [II]: UKW = 'B [A19615] but  these have now  been replaced with army wheels A13522 [II],
     A10218[III] and A14133[V]: information courtesy of Niels Faurholt [see also footnote #136]. A19608, A19615 and A19723
     have similar features (yellow Steckerbrett). However, A20531 and A20662 are rather different. They each have a sand-
     coloured  (beige) cover over the wheels and bulbs and a black Steckerbrett.

       M10215/jla/44 the fabricator's code and date are patently incorrect. The 'Zur Beachtung' plate in the lid is inappropriate.
¹²⁸  no wheels except UKWB A7889: badly damaged: offered on eBay January 2008
¹²⁹ 'repro' wheels  A16129 [I, II, III] and UKWB plus original  A18255 [ [II], A4073 [V]

¹⁴² seen at National Vintage Communications Fair, at the Warwickshire Exhibition Centre, UK: May 2008
¹⁴³ this is one of two  machines purchased for evaluation by the United States in 1928  - the other was A772:
      wheels are the original I, III and III plus reflector. Strictly speaking A766 is not an Enigma K: that term was
       not yet in use in 1928. A766 and A772 should more properly be labeled Model A27 - their Chiffriermaschinen
       AG  internal designation: functionally they are Enigma K machines with  minor  cosmetic differences.
¹⁴⁴ all ten of these Enigmas are presumed to have non-standard wiring [probably the same as A1242]
¹⁴⁵ wheels are M18196 [I, VIII, Gamma, UKW=B] and M16430[VII]

¹⁵⁴ wheels are A7424 [I, II, III], A02192 [IV, V]: UKW=B [A01400/44E]

¹⁵⁸ wheels are all A598 [I, II, III]: UKW=B [A18840]
¹⁵⁹ there are features of this Enigma that remain unexplained: the three wheels appear to be of the late-war type: there is no
      UKW - the space is filled with the wired core of a regular wheel
¹⁶⁰ wheels are A17534 [ I, II, III]: UKW=B [A14390]

¹⁷⁷ wheels are all A20156 [II,III,V]: UKWD=A5436
¹⁷⁸ wheels and UKW (K)907 [I,II,III]: Baseplate stamped K375. No 'K' on wheels. Case marked '907' in script
¹⁷⁹ wheels are all A01891 [III,IV,V,UKWB]
¹⁸⁰ wheels are A603 [I,II], 02194 [IV] marked '52-E', UKWB=A12430
