Dear Mister Bernard Willson,
You are our expert of C38 Hagelin cipher machine. Hut 4 needs you to decipher the following message.

We have intercepted it from 37°09′13″N 26°51′25″E.
Please, decipher it. This should be easy.
A spy sold us the key and we believe that the message begins by one of these cribs :
