[Pibwl]

It might be noted, that in 11/39 - 2/40 and 7/40 - 10/40 there were no tanks in Polish units available, and in 11/40 - 3/44 Polish tanks were used for training only (in UK and Egypt/Palestine). They could have faced some invasion however...

Next:

(mainly class 13 Med tanks)

12 Valentine III - this variant was used only from 2/43 until at least 11/43 (now 11/41 - 12/42)
Photo shows some 3-men early variant (as in the British OOB)

13, 14 Valentine IX - similar Valentine VIII is known to be used by the Polish, from 2/43 until at least 11/43 (now 7-12/42 for #13, 1-12/43 for #14 with AAMG). There is no information on Polish Valentine IX.
There are no AAMGs on photos of Polish tanks evident (and it was not, that only after 1/43 all 6pdr Valentines were fitted with AAMG - so they might be two options of the same tank, or merged into one, either with, or without AAMG).

448 Valentine II - used from 11/40 until at least 5/42 (now 7/40-10/41). (Possibly earliest were Valentine I, but it's essentially the same).


By the way, as for Valentines in all OOBs: in Valentine III and V due to increased weight, side hull armour was reduced from 60 to 50 mm, and in VIII-XI - to 43 mm (now they all have 6). Turret rear (at least in 2pdr variants, but maybe in all) had 60 mm (according to some sources, even 65 mm) - now it has 5.


18 Sherman I [as CS tank] - generally 75mm Sherman I wasn't used by the Polish. It should be changed to Sherman III, which was a basic tank of the 2nd Arm.Bde on Italian theatre, used from 10/43 until end of 1946 (now 1/43-5/45).
Photo is M4A1 Sherman II - could be 27725 or 27726.

(I omit Infantry Tank Shermans mentioned before, to be removed IMO)

21 Comet - wasn't used by the Polish.

24, 146 Centurion Mk 1 - sci-fi unit in Polish case.

26 Sherman I (Med tank) - as unit 18, should be replaced with Sherman III, used in 10/43-12/46 (and fitted with AAMG).

27 Sherman V - used from 10/43 (OK) until 11/44 in combat units (now 12/46). (I'm not counting Polish training units in UK, which sure used them longer. In case of the 3rd war they could have been used)

28, 125, 130, 200 VC Firefly - I suggest name Sherman Firefly - there are only Fireflies VC in this OOB, and a difference between Firefly IC (which was also used by the Polish) is not worth mentioning.

Units 28 and 200 [class Gun tank] should be merged into one IMO. The only difference is, that #200 is available in 6-7/44 and has radio code 0, while #28 is available in 8/44-12/46 and has radio code 1, which is strange, since it should be more popular with time, and there's nothing, that could replace it in Sherman troops.
IMO there should be only unit 28 left, with a radio code 0, available from 6/44 until the end.

29 Sherman IB [CS tank] - used from 2/45 only (9/44).

33 Crocodile - wasn't used by the Polish.

The only flame tank used, that could be added, was Wasp IIC (#128 in British OOB), used probably from around 6/44 (no closer date). Photos of Polish vehicles show, that they also had external Bren mounted (same could be for the British OOB).

To finish with class 13 Med tanks:

438 Grant I - should be removed - there were only few recovered Grants used for training as non-standard vehicles. 3 were used as command tanks in the 2nd Arm.Bde. staff.

441 Crusader III - used from 9/42 until some 5/44 in the 1st Arm.Div. (now 4/42 - 4/43) (in training units used even longer)

442 Crusader II - used from 9/42 until some 5/44 (now 1/42 - 9/42) (used mostly as command tanks, so we can finish with them earlier as well). Late tanks had removed BMG turret.

443 Crusader I - not used by the Polish, especially from 5/41

444 A13 Mk II - not used by the Polish.
Should be replaced with A13 Mk III Covenanter (986 in British OOB), used from 5/42 until 11/43. Radio code should be 0 or 1 (now 2 - it was less numerous and worse, than Crusader).
An interesting fact is, that Polish Covenanter is regarded as the first tank knocked out on the British soil by the Germans (bombed on 1/6/42).

474 - FR Somua S-35 - to be removed

477 - H-35 - as I wrote, few were used for training - might be removed.

I'll deal with formations later.
