Mant thanks, Fernando!
Let turn the question: IF the underwing letter toward the wing tip can be read, will the third letter on the fuselage be the same? The reason for asking is the plane of Erich Groth. In the German vermisst list the plane is coded M8+TC, the letter T however is written with pencil and must be added later, not machine typed as the rest is. The attached photo is from Pori in Finland 4 days before Groth and his Bordfunker were killed in a crash in the moutains in Hallingdal in Norway 12. August 1941. As can be seen from the picture, the left underwing letter is K. So, when the letter 1,2 and 4 is known, the coding must read M8+KC?
