Bf110-E Werk Nr 3863, major Erich Groth

[carlmu]

In August 1941 Major Erich Groth was photographed in Pori/Finland with his Bf110-E where three of the four code characters are easily read as M8- C. The missing letter is supposed to be a T or K, that is either M8+TC or M8+KC. Anyone know the correct code?
The plane probably had Werk Nr. 3863. Does anyone have the history of this plane?
On the engine cowling there was written an uppercase A side by side with three dots in a triangle. I thought the E-series was equipped with the DB 601N (P) engine and was marked with an uppercase N to indicate the need for 100 octane fuel, according to John Vasco's excellent book about the Bf110-C/E. But does the A indicate another engine than the 601N? 601A?
Major Groth and Bordfunker Herbert Muche flew from Stavanger in South West Norway to Kirkenes in the North on August 11 or 12 in 1941. They were supposed to make a fuelling stop in Trondheim, but never arrived there. The weather along the route was bad with 0 deg Celsius and snow in 2000 m height. The crashed plane with its crew were found a year later. Remnants of the Bf110 still resides in the mountain in Ål in Hallingdal, 1500 m above sea level.
It would be very interesting to know if others can contribute further to complete this sad story, which I hope to complete soner or later.
I know a little about major Groth, but nothing about Obfwd. Herbert Muche.
