Geissler Tube Boxed Set 1890’s To1900?? Motor Tubes Batteries Etc:
Boxed Geissler tube set from France. Please look at all the pictures and ask questions. I’m certain the set is not complete and it’s operating condition is unknown. The one grenett type battery has a glued chip in it which is pictured. The catalog has a lot of interesting illustrations in it. I don’t know how to test any of this so it is sold as is.
