Polish OOB2 corrections/suggestions (v.6)

[Pibwl]

Aircraft - continued.


601 PWS-26 [AOP aircraft] - this in fact should be available since 9/39 only (now 1/37), because it was a trainer during a peacetime.
Same for 616 RWD-8

607-612 Fokker VII/3m - according to A. Morgała, military variant was named Fokker VIIm3W. In fact, max speed was only 185 km/h (now speed 3)

As for units 609 and 610, the sources don't give details as for its load (1000 kg), but it seems very doubtful, if Fokker could carry 300 kg bombs. 200 kg bombs were unknown in the Polish service at all.

464 PZL P-23A Karas - name should be just "PZL-23A Karas".
It was introduced to units from 9/36 (now 5/36).
MG should be #190 wz.33.
Due to weaker engine, more likely armament of A version would be 8x50 kg bombs rather, or 4x100, 4x50 max (now: 5x100, 4x50)

613-615 PZL P-23B Karas - name should be "PZL-23B Karas". B variant was introduced to units from spring 1937 (now 11/36)

9 bombs is too much, it could carry 8 big bombs only.
As for unit 613 it would be 6x100 kg and 2x50 kg (though practically used load was up to 600 kg)
As for unit 614 it would be 8x50 kg

There could be added variant with 24 x 12kg bombs, if it's useful.

Weapon 194 100kg Bomb could in fact be changed to 110 kg Bomb, which was its real mass according to a monograph on PZL-37 Łoś (they were German WW1 PuW bombs and Polish Ż wz.31)

Weapon 196 Myszka Bomb should be named ".. bombs", or in fact "bomblets".
BTW: all weapons "Bomb" could be renamed "Bomba" in Polish (like in Italian oob)

617 PZL L-2a - name was just PZL L-2. Precisely, used from 9/30 (now 1/30 - at that time, a prototype haven't flown yet)

618 RWD-14b Czapla - serial variant was named LWS Czapla. It was introduced to units from 5/39 (now 8/38)

619 LWS-3 Mewa - should be available from 9/39 only (7/39) - few introduced in a hurry after a start of war.


620-622 Farman Goliath - speed was 154 km/h, so it should be 2 (now 3). As for unit 622 - last were cancelled by 11/35 (now 12/36)

624, 625 Potez XXV A2, B2 - name of both bomber variants should be B2.
Morgała's book mentions max bomb load: 4x50 kg and 24x12 kg, without 100 kg bombs. Unit 624 could be armed eg. with 24x12 kg only. There could be some 12 kg bombs added to unit 625 or not.
There should be only 1 fixed MG.
Max speed of bomber variant was around 190 km/h, so it should be 2.

627 Potez XXV A2 [AOP aircraft] - Potez modified with radial engine should be rather Fighter-Bomber class, with armament as above, but speed 3 (232 km/h), used in some 8/38 - 5/39. Name should be Potez XXV B2-BJ

Ammo-related question:

You write here http://derela.republika.pl/weap.htm#am that the Polish army had AP and API ammunition for the 7.92mm machine guns. Were those ammo types commonly issued to armored vehicles and do you have any data about their armor penetration capabilities? Is there any evidence that they were used against German armored vehicles in 1939? I suppose they were of conventional design with steel core?

There must have been an error in source, because now I read in other books, that PS should be APT round, not API. Anyway, P bullet was an equivalent of German WW1 steel core SmK, and APT was its modification.

In case of infantry wz.30 HMG, for 2000 rounds there should be 1766 ordinary SC, 200 P (AP) and 34 PS (APT). I have no idea how they were belted. Unfortunately, I haven't found information how common they were in armoured vehicles. I may assume, that more common, than in infantry.

I have no data as for armour penetration, but it should be no more, than some 8-9 mm - enough for own tankette, but not enough for PzKpfw I...

Mistake as for year - it should start in some 8/37. We don't need another type of spotter plane, but it
According to Morgała, all Potez XXVs (units 624-627) should be armed with #190 wz.33 MG, not Vickers.

There should be also added Breguet XIX B2 - there is already icon 2906 with Polish signs. Used in 1/30-12/36. It could be copied from Spanish Republic 410, as Level Bomber or Fighter Bomber or both. It could carry 8x50 kg or 4x100 kg bombs, was armed with 1 x 7.9mm Vickers MG and max speed was 213 km/h (2? 3?).
