Aircraft over Dunkirk may 10- June

[Planejunk]

I am doing a project and need to get units, identification call letters and paint schemes for aircraft operating over or near Dunkirk during the evacuation. We plan to build a full size section of the front half of a He-111 for our project and a couple of others. A Spitfire, Hurricane and Bf-109E. I've been looking and am fairly sure of the paint for the Aircraft, they seem to be standard for the period. Units and individual markings are needed. Any help would be appreciated and credit give with display.
I found the units for the Spitfire and Hurricane but would still like varification. Also was the He-111 units KG-4 and KG-27? I think I have info. For an He-111. 3/KG-27 10 May 1940. 1G+DL crew Uffz. Otto Wehmieier (Pilot).
In an earlier post on this site was a JU-88A-1 L1 or I+AP 5/LG1 crash in Belgium at Nieuwport beach May 29,1940.
I have about 800+ original photos of crashed or damaged aircraft from 1910 till Gulf war most are WW-11. So, if I can help anyone let me know.
