Ok guys, here we are. I made a quick research, get some photographs and looked a few books, and this is what I get

.
At first sight, from what I have seen, it looks like, while in Poland Luftwaffe was in an upgrade process, many "old" (because only months before they were "brand new" ones and "the best" Germany had) aircraft were used yet on Poland. Later even over France, and it's supposed to reach BoB (but that's a very old affirmation and I wish to see those photograph of early 109's fighting over England and it's date), they were used also but the less the more time goes by. Anyway, what "old" aircraft were used on Poland? Well, many old books say and show us (but usually profiles, no photos) Bf-109C, Bf-109D, even some Bf-109B. Ok, but what I have seen now? I didn't found evidences of any Bf-109B over Poland, on that date they were all of them (at least what I have seen) on "Fliegerschule" labour. But more of that, first I tried to paint some Bf-109C, you can find a bunch of them supposed on Poland in old books, but in modern ones, and with photograph of that, I weren't able to find any evidence of Bf-109C on Poland or even later while it's claimed on old books they were used until 1941 in Norway next to Dora model on night fighter duties, but those aircraft in Norway from NJg1 I have seen photograph are all of them D model and nobody can confirm they were C

.
I told around here, on SCW theme, lately I have seen not only there were no C model on Spain, but it was made on very small numbers and changed quickly by D model, so many of the C claims are in fact D. After see anybody can really confirm a C model over a photograph nowadays I have to say probably those researchers are more than right when present us a very rare C model.
So, as said, I tried to paint C model, but it was very hard to find and I could made only two of them, moreover later I saw they were really D models...

so only D models (and not a lot of them but a bunch) I was able to paint for early Poland duties you wanted. Will try later to paint some (very few) B models not in schools I have seen, but they were previous to war, keep that in mind, so I don't know really if they are useful for you.
And there is the result,
Bf-109D-1 from Jg71, that shark mouth is very well known. Anyway, it was claimed to be a C model in the past, really it's a D model, five skins...

Bf-109D-1 from Zg2, as you know in Poland many unit destined to Bf-110 wasn't supplied yet with the model, so they used "old" D models, four skins...

Bf-109D-1 from Jg2 "Richtoffen", previously in 1939 the unit was named Jg132, renamed but retaining it's unit markings, three skins...

Bf-109D-1 from Zg26, same case as Zg2, this aircraft was also claimed in the past to be a C model, it's a doubt but probably is a D like all of them, one skin...

Number of skins in every unit are not random, I have seen every skin done on a photograph!! Zg26 one is alone because of that, and didn't made more skins from other units because same reason, only one aircraft available or unidentified or same unit but another staffel and alone on photograph, so I stopped. You requested them for campaigns so I thought it's useful being various numbers by unit than one skin alone by unit. Anyway, at a first sight there were not much more information or photographs about those aircraft so I can work on much more because I have no much more. Hope you like and use it.
DOWNLOAD POLAND 1939 BF-109D SKINPACKMore coming!! I was aware time ago I haven't seen any Emil 1 adequate void, so with Dora and Emil 4 ones I will make it and upgrade my Emils SCW pack. Not sure if I have ever posted here my Emils SCW pack (previously used on various "films"

) so I will post them now anyway. Also when upgraded will see to make some Emil 1 over Poland and BoF skins using same accurate pattern and colours from D model now I have it. I think Emil on RLM 70/71 is also a nice one, not everything is 71/02/65

Enjoy!
