Seeking ID of strange "cheese grater" device on below cockpit window of some 1940 He111s

Many thanks Larry.

Here are two other photos.

In the first the flare chute, on this KG 26 machine, seem to have some kind of light covering. I suspect this was to stop airflow entering the chute holes, in a similar fashion to the Battle of Britain Spifires and Hurricanes had their gunports 'papered over' with a red light canvas.

The second photo shows the interior of an He 111 showing the signal flare gun pouch which perfectly matches the beautifully executed A. Grainger drawing in Aerodata International No 12 Heinkel He 111 page 229
