I bought this little box on some kind of flee marketstore this morning for 5 euros. Looks like Pre WW2
I will describe it and I placed some pictures also. It is not really liveleak material, But I am very curious, Thanks in advance!! Sorry for the flamboyant backround. My mother made me a quilt. :p

The plate in it says: J.A,F, Best, Instrumentmaker Leeuwarden. (L'warden = Dutch city)
It has a little drawer for I guess additional tools and/or parts.
On the full picture with all element in their places that there is one glass thing with two holes (One compartment) So no ancient battery I guess. Right behind it the single thing, far left. is also an element. See other pictures where I took it all out. On the longer black thing is printed: ELEMENT- KOHL F ------ C CONRADT

Update one. should be from 1898-1899, medical equipment
J.A.F. Best was member of the Frysian museum 1917.
