[piters]

Hello,

I have the German abbreviations of He-111 5-men crew functions.
I'm not very good in German, so I'm not sure in certain identification.
Please, could you help me explaining the abbreviations as follows?

F (I presume it's a pilot)
B
Bf
Bw
Bs

B - bombardier, the others - gunners?

Thanks in advance.

Regards,
Piotr
