FF33 field phone was a workhorse of the field communication of the German army, but nothing works without power source, so there was during the course of war need for enormous amount of those field elements. @Alperator has nice page about them here http://der-fernmelder.de/zubehoer-nachrichtentechnik/feldelement-f30-luftsauerstoff-element-t30/ I'd like to put up a list of all known manufacturers of those field elements, so if anyone has any Feldelement in their collection, bring the nice photos in!

very good idea, I look the days at all the batteries I have. but it has to be distinguished from T 30 and F30. T = Dry-elemet F = Filling element Filling elements were mainly used in fortresses
