so many questions. first it is not known precisely if Oskar flew Weiße 14 in Sturmstaffel 1, I have found this may not have been exactly true. not all Sturms had the badge but most did. all had the s/w/s fuselage band worn. no yellow painted undercowling and not all Sturmstaffel 1 a/c did either.
for Maxi that may not have been his usual a/c as he flew 4-5 different ones, this a/c is not really even a sturm A-8 as it was used on jabo missions in Normandie and then armored up in an upgrade., the yellow stripe would of indicated 12th staffel machine and the spinner stripe was removed and later painted over white as all the a/c of the gruppe later in August of 44.
june of 44 all 11th staffel machines had the wide white band and none painted over that came later in July end and into August before all the colors were painted out and new a/c came into the gruppe. each staffel had 15 a/ac according to Strum JG 3 vets. 1-15 so all the ones you have named existed.
Weik in an interview told us he never flew a white 1 and that he felt he would of been found out by US P-51 pilots and shot down.
not sure why all the camouflage scheme questions as the whole gruppe was pretty much the same with slight variations in tone on the fuselage. the whole colours were in June/July of 44 during the first Sturm missions. after their airfield had been blown to pieces at Memmingen in mid-July of 44 the bright distinctive colours were withdrawn and the a/c were left to decompose in the weather and high altitude missions. new a/c coming into the gruppe to replace the shot down ones were left in the typical 1944 two-tone greys and white spiralschnauze on the prop.
Ungers 3 17 in may of 44 was not his as the photo is a propaganda one. I have 6 photos different from Willi in fact a copy of all his photos from his album, some very unusual ones as well with including a special number black 8 Sturm he is standing in front of. yellow 17 with the stupid rear facing rocket mortar had a white band with a ~ over it. the band again was standard with the IV.th gruppe ~ marking from May as the unit transferred out its Bf 109G-6's to Fw 190A-8 and A-8/R2's. In Willi's logbuch he does fly a different A-8/R2 fully loaded Sturmjäger numbered Gelbe 17.
here is what happened in June at the end and through July of 44 before all the 4 staffels had the same a/c in the same camo and the only difference was their staffel number colors.
11th staffel black adlerflugel with white trim and white spiral, black solid numbers, some but very few had white trim
12th staffel black adlerflugel with yellow trim and yellow spiral, solid yellow numerals
13th staffel had the same as 11ths staffel except white numerals solid
2./JG 51 had red trim on the eagle with red stripe on the spiral, red solid numerals, this later as it became the 16th staffel of the gruppe removed the red from everything and the black eagle wing exhaust camo and just had red numbers only.
there are many variations just like the propaganda photo of Schwarze 8 that has W. Maximowitz riding in for the camera crew in June of 44.
there is more of course, purchase Dr. Jochen Priens IV./JG 3 from Struve Druck Verlag in Eutin, Germany for more though black and white pics, but you can see how the Sturm a/c changed in camo over the weeks in the summer of 44.
Don you owe me a very large Deutsche Bier for all of this.......
or maybe a Christstollen for Weihnachten
anymore questions I will gladly try and help and try not to confuse you....
