5th Bonus

25 januari 1940

 

Bste herr Gyldn,

 

Jag fljde ert rd och uppgraderade min maskin "C38" enligt era

rekommendationer. Snart ska jag ka till USA fr att slja maskinen.

Fr att bevisa dess osrbarhet, har en anstlld krypterat ett lngt

meddelande p engelska. Detta meddelande kommer att bli en utmaning.

Men jag tror att ngon amerikansk expert (inklusive Mr W.F. Friedman)

kommer att kunna dekryptera det. Skulle ni kunna gra det?
