KG26 A/C Codes 15 Aug 1940, Shield Colour

[BoiseBlade]

I am looking for some possible clarification on the aircraft of III/KG26 that participated on the 15 Aug 1940 raid on England. I am currently building a HE111 H4 which I have read that some or most of III/KG26 was flying at this time. (Hope it is accurate) It seems the only confirmed A/C code lost was FS of the 6 A/C lost from the Staffel. Wouldn’t that have been all but 2 or 3 L? What I would like to try and find out is if it is known what colour the A/C letter was and the KG shield for this staffel. I would think from my readings that Letter would be RED and Shield RED with Black Lion. But I see there is a lot of information out there including “atckyrre” Post on 1 Jan 06 about this, So I am still confused.
I wonder if all 8/KG26 aircraft A-H/I participated this day.
I also have a question on if A/C code outlines were used at this time or were they used later with this KG? the image attached is just from the web of A/C 1H+EK that appears to be maybe a H4 variant but no time frame found.
As an FYI, I choose this KG because of it’s participation in the North of England. My wife’s family 3 generations back came from outside of Middlesbrough in a place/town called Eston. She has copies of pages of a journal from distant uncle or cousin with dates 30 May 40 stating days ago we were bombed by the Germans but not close. Also just Aug 40 that said we have had many raids including a big one some days back. Not much detail I know….
Thank You
