Came across this, today. Can anyone identify it, please? The base of the box is sealed with wax. When the lid is down, the whole thing is 130 mm high. Thanks, Lawrence -- Attachments:

Tunable or otherwise adjustable spark coil? Does the lower knob rotate or pull out? Resistance between terminals? Chrs, DC

Tunable or otherwise adjustable spark coil? Does the lower knob rotate or pull out? Resistance between terminals? Chrs, DC Sorry for slow reply. I should be doing something else so this counts as a Displacement Activity. The bottom knob is just another terminal, apparently unconnected to anything else. The top two terminals have about 20 kilohm between them, but judging from the way the meter behaves there is quite a bit of reactance there too. Some resistance between the top two terminals and the big silvery terminal at the very top, in the lid. Again a lot of jumping about. Are you aware of similar items? Any idea of age? Thanks!
