For a description of the format and data included in Production Tables, see here.

Produced Variants (See Note 1)

A.W.41 Albemarle B.Mk.I 5 crew mid-wing, cantilever monoplane medium bomber with twin fins and rudders and featuring a tricycle undercarriage and
  using non strategic materials. Based on the Bristol Type 155 (although this is disputed by Williams [3]) to Specification P.9/38
  and later Specification B.17/38. Design was transferred to Armstrong Whitworth and the requirement changed to
  reconnaissance bomber to Specifications B.18/38, to meet the requirements of OR.60. The first prototype initially featured
  short span wings and small area fins and rudders. Boulton Paul four gun dorsal turret and two gun manually operated ventral
  dustbin'. Two 1,590 h.p. Bristol Hercules XI powerplants.
A.W.41 Albemarle S.T.Mk.I Special Transport version of B.Mk.I; bombing gear and dorsal turret removed, replaced with hand operated twin-guns under a
  sliding hood. A freight door added on the starboard side.
A.W.41 Albemarle G.T.Mk.I Glider Tug. B.Mk.I fitted with Malcolm glider towing gear.
A.W.41 Albemarle S.T.Mk.II Troop Carrier. S.T.Mk.I with seating for 10 paratroops and a dropping hatch in the floor.
A.W.41 Albemarle G.T.Mk.II S.T.Mk.II fitted with Malcolm glider towing gear.
A.W.41 Albemarle Mk.IV Mk.1 with two 1,600 h.p. Wright GR-2600-A5B Cyclone 14 powerplants.
A.W.41 Albemarle S.T.Mk.V S.T.Mk.II with fuel jettison equipment to meet the requirements of OR.173. Dorsal turret retained.
A.W.41 Albemarle S.T.Mk.VI S.T.Mk.V with larger freight door.
A.W.41 Albemarle G.T.Mk.VI srs.i S.T.Mk.VI with Malcolm towing gear.

Notes
  1. The Mark numbers allocated are clearly defined in the RAF contract delivery cards. However, role designations are not, but are given in most publications on the Albemarle, and those from Tapper [1], Bowyer [2] and Williams [3] have been reviewed here.
    In addition to role designations, both Tapper and Bowyer allude to series suffices. Definition of Mark/Role/Series designations can be found in the Produced Variants list, but note the following:
    • This author understands that the use of "series ii" with respect to Mk.I aircraft relates to the addition of glider towing gear. As such, the use of a series ii suffix with G.T. (Glider Tug) role designation is superfluous.
    • The use of a "Mk.IIa" and "series iii" by Bowyer is both unique to him and undefined. As such, they have been omitted from the Produced Variants list.

    Finally, the usage of the four gun dorsal turret is unclear. It is indicated that it was removed on the S.T.Mk.I, but most photographs of that Mark show the turret fitted. Does that mean that it was fitted to G.T.Mk.I aircraft? Also, the Mk.V is indicated as a Mk.II with fuel jettison, but any MkV photos I have seen clearly show a turret fitted.

  2. The Hawker Siddeley Group formed a new company at Brockworth, A.W. Hawksley Ltd, to be responsible for the assembly of the Albemarle.The aircraft were assembled using sub assemblies that came from more than a thousand subcontractors, including Harris Lebus Ltd., the Rover Car Co. and MG Motors.

  3. Per Albemarle contract delivery card, it was initially intended that the aircraft "be produced alternatively for bomber and G.R. use and will be modified with de-icing or barrage balloon cutter gear.
         1st 70 a/c neither wing de-icing nor barrage cutters.
         ii) Approximately next 130 wing de-icing only.
         iii) Approx: the 200th a/c onwards, produced in batches of 50 alternating between
              a) those fitted de-icing.
              b) those fitted barrage balloon cutter."
    It is not known how much the production aircraft followed this memo.

  4. The first part of Contract B.53250/39 to A.W. Hawksley, per Requisition No. A.A.1/E.11/39, was for 2 Mk.I and 100 Mk.II in batches between V1598 and V1759 as indicated.
    The second part, per Requisition No. A.A.1/E.11/42, was initially for 550 Mk.IV, beginning with V1696 - V1723 and continuing through V2068, followed by LV482 - LV623 and NG506 - NG754, all in the indicated batches. This was then reduced to 300 Mk.IV aircraft V1760 - V2068 and LV482 - LV623 in the indicated batches, until finally only one Mk.IV was ordered, along with 49 Mk.V, the remaining 250 becoming Mk.VI.
