[Hohlladung]

#193:

Herr Großadmiral,

The word is most likely a staff unit and could read:

Ci 4 Pers.

Does that makes sense?

Best regards

I read it as
"Kirkenes"
which is a town's name.

Thanks Hiltraut,

That makes sense.

What I read:

Großvater C.'s 80. Geburtstag 13. Ⅲ. 41 [13. March 41].
Berlin NW 87, Flensburger Str. 17 Ⅳ. [the Roman Numeral "IV" could mean 4th floor]

Familie C ohne Mechthild,
Anneken u. Walter Leist
Großvater's Tölzer Freund Grienke.
