"B.W.E Rechengerät s. F. H. 18" artillery equipment?

[collector15]

Hello guys, I´ve acquired this item. It´s a textille case with some charts with various informations about wind, temperature, distance and so on. Looks to be complete. Is this item common or not? Any info about use of this thing would be appreciated.

Hi

Never seen one before.... i would say not too common

I don't have much info, except it is for the schwere Feldhaubitze 18, and N.f.D. = Nur für Dienstgebrauch....

Nice item !!

Hello,
Tom's right, it's not very common. I've seen one before but the cloth carrier was empty, all contents were long time gone. The front markings were also more faint than the ones seen here. The only thing i knew then is that it was meant for the 15 cm field howitzer....great item you have there, congrats.
Thanks
