114 Panzerbuechse - there were 568 PzB 39 in 9/39 available (now starts at 1/40). There is only #250 FJg PzBuechse available from 7/39, but I don't think, that they were used by paratroops only then (and the paras generally weren't fighting in Poland at all)
BTW, the weapon could be better named just PzB 39, not 38/39 - 38 was a semi-auto weapon, which wasn't finally accepted and found very limited use, while PzB 39 was a different mass-produced weapon. Since they aren't available before 1939, there's no need to bother with marginal PzB 38, developed before 1939.
Maybe it's a good idea to rename "Panzerbuechse" units to indicate PzB model?
318 15.2cm Batterie - I'll attach proper picture of Soviet M-10 howitzer (now it's late-war D-1)
335 4.5cm PaK 184/1 - it has a picture of short-barrel gun. A proper picture for long barrel 45 mm is eg. Pm29366
346 MG08/18 MMG Grp - has first availability date later, than second
425 PzSpw.AB 41 - it would be worth to find a photo of specific German one. I'm attaching one proposal.
434 SdKfz 8 - current picture is SdKfz 7, what is evident by spoked wheels. I'm attaching a proposal.
467 PzKw T38 732(r) - the picture is actually T-37
495 GebJg PzBuechse - picture used in the game for 13.2mm ATR is 309 (I'm not sure however, if it's not PzB-39) - now it's probably 20 mm Solothurn. I'm attaching alternative 309 picture of 13.2mm Mauser.
570 PzKpfw Ia - it's a matter of months, and Jentz does not write clearly here, but starting date 7/34 is too optimistic - seems, that none were operational before 1/35 (first armoured divisions were being created during 1935. It might affect formations.
586, 587 P174/178 L204f - AFAIK there was no such car, as Panhard 174, just 178, and its German designation was for sure P204(f). I think, that German designation "P204(f)" should be enough, or "Panhard P204f". I'm attaching German pictures to replace generic one.
600 Panzerbuechse - picture - same as 495 above - now it's PzB-39. I'm attaching alternative 309 picture of 13.2mm Mauser.
BTW, what's a difference between weapons #142 Mauser T-Gewehr used by unit 600 and #90 13.2mm Mauser used by unit 417?.. AFAIK it is the same weapon.
601 Panzerbuechse - proper picture for Polish wz.35 AT rifle is 23510 (current 115 is PTRS - same situation in Polish oob)
603 Pzbuechse SS - correct weapon's designation is PzB M.SS.41, not MPzB 41
604 Ost Pzbuechse - picture should be Russian PTRD (eg. 23151 or 27105)
605 Ost Pzbuechse - pictures should be Russian PTRS (eg. 23150 or 27106).
734, 793 MG249(p) HMG - I can't find such designation, but if it's Polish wz.30 Browning (what suggests letter "p"), then picture 29695 would be more appropriate (now it's Vickers).
817 4.5cm PaK 184/1 - as unit 335 - proper picture for long barrel 45 mm is Pm29366
834 PzKw IIa/b - photo 27513 shows later variant, not initial a/b (small letters), which had six small roadwheels on a frame (there were later variants A/B with standard chassis, but availability dates suggest earlier ones)
842 SdKfz ADGZ - ADGZ is never used with "SdKfz" (which was used with numers only, btw). It could be names Steyr ADGZ (
http://de.wikipedia.org/wiki/Steyr_ADGZ )
867, 868 630(r)3.7cm PaK - should be 630(f) (French) (or just UE instead of number)
875 sFH 13 LrS (f) - it has apparently picture of Marder I - could be just 0032 instead, or new picture with grey camo
(It should be armed with 15cm sFH-13 howitzer, with longer range, than sIG-33 infantry gun).
577, 939 PzKw B-2 740(f) - actually "B2" without "-".
925, 926 Do 17E, 17P - new picture of this "flying pencil" would ne nice - now it's late-war Do 217. I'm attaching a proposal.
927, 928 Do 17Z - I'm attaching a proposal picture for Do-17Z - now it's late-war Do 217
954 Pz T34a 747(r) - picture is T34b with F-34 gun, not earlier one with L-11 gun. I'm attaching a proposal in German service.
968 sIG38/2 (t) - according to Jentz's Panzer Tracts, apparently only one experimantal vehicle was produced. And it was open-topped.
976 sIG38/1 (t) - according to Jentz, it was produced only from 12/43 - now 5/43 (earlier there was older rear-engined model). This source recognizes old and new model as "Gw 38 fur sIG33/1" and "Gw 38M fur sIG33/2" respectively, or Grille and "Grille ausf K". In short could be "Gw38M sIG33/2" or Grille K.
978 SturmIG 33B - German short designation was StuIG 33 (without B)
997 Horch Kfz.70 - picture is Krupp Protze (Kfz.70)
