He 111H-6 from I./KG26....code?

[lucky13]

Is it in any way possible to find out the code for this machine, a He 111H-6 from I./KG26 other than 1H+?? It had to do an emergency landing at sea south of Svalbard, after a mission on 13.09.42 . It has the Wk. Nr. 7567. The crew was picked up by a U-boat but the U-boat never returned and they're all since then MIA.

Crew,
Lt. Arnold Harnau (F) MIA
Uffz. Werner Telgenwerth (B) MIA
Uffz. Walter Kullick (Bf) MIA
Uffz. Friedrich Trunner (Bm) MIA
