Welcome mark!
You have found Polish "Sturmovik" forum section dedicated to planned "9/39" add-on for "BOB". As you can see, this is Polish-spoken section, but rest assured that your questions will not remain unanswered - we've got some people who speak English, like yours truly
In case you wanted to continue the discussion, I invite you to our English-spoken section at:
http://www.9-1939.pl/phpBB2/1) The Henschel Hs 126 (probably A-1, but maybe B-1?) from
3.(H)/21 (3rd Staffel of Aufklarung Gruppe 21 scouting for XIX Panzer Corps, side code
P2+....) flown by Leutnant Friedrich Wimmer & Oberleutnant (navigator) von Heyman was shot down by
por.(lieutenant) Marian Pisarek, 141 Fighter Escadrille, III/4 dyon (the squadron from Toruń), together with his wingman kpr.(corporal) Benedykt Mielczyński. Skalski was in second pair (with por. Karol Pniak) that supposedly aided them (but Pisarek's post-combat report did not mentioned it). After the Henschel crash landed in the field, Skalski landed near it, patched up the wounded von Heyman and took Wimmer (hiding in the woods) as POW using a ....zippo, because he left his VIS pistol in the base!

He also captured German maps with sensitive information marked on them.
The Committee that confirmed air kills, set up at the end of the war, led by płk.(colonel) Jerzy Bajan, confirmed that Pisarek and Mielczyński get 1/2 kill each. Skalski's claim for 1/4 kill was rejected.
But don't blame the guy for colorizing his book "Black crosses over Poland" by saying he downed the plane. It was written in prison, after 8 years of tortures from the hands of communists...

no wonder that his memory was failing him.
2) The Kampfgeschwader 1 "Hindenburg" (side code V4+....) used Heinkels He 111, both E-3 (...well some "E" for sure) and H-1 version. Both I. & II. Gruppe and Stab Staffel had a total of 83 bombers on September the 1st, 1939 - 65 of them were fully operational.
