In a heinkel 111 the SLD flare gun was a part of the communication equippment,the aircraft radio operator got the code flares and flare gun in a leather case or a little wood box before mission.The flare code system vas used when other communication system was none operative.This information i got from a old KG100 pilot,he flew his Heinkel in norway in april 1940.it was possible to opend some of the small cockpit frame windows,i think one of this windows was used if use of flare gun was wanted.

You have pictures of the flare gun ?
