I am looking for addittionall info on this one please.

Recently discovered:
Teak wooden device with glass for containing acids and carbon(?) rod

Golden name plate (1.6 gr) says 'J.A.F. Best instrumentmaker Leeuwarden' (The netherlands)
Dimensions (without steel handle)
Height: 11.5cm
Witdth: 13cm
Depth: 13cm

Materials:
Bakelite, teakwood, steel, copper and gold. (18.2 gr in total)

The two elements above the acid are made of gold.
Betheath the name plate is a very tiny lkogo with a lightbulb the text says 'schutz marke' (Registered name in German)

Alot of traces from using it on it. even on the golden name plate and inside of the case. Also the bottom side of the gold is deteriated from the acids used.

It has 2 tiny locks, one of them 'hidden' Only visible when the case is opened.

The two posts on right front are for connecting a battery to the unit.

My guess is it was made to test "samples" of something.

Looks like a variation of the Seymour Battery device?
