What's this one.

[Batz]

I saw this on ebay Australia, the seller does not know what it is and it has me stumped as well.

Looks like a carbon arc torch, used for melting battery terminal lead to join  cells, make small repairs, etc.
(hard to tell for certain without seeing the tip, but that's what it resembles)

Dynamite detonator?

[Branson]

Nut cracker?

Pneumatic jumper cables. Hook it up and pump up your dead battery?

It can't be a Polish battery charger, it's in Australia....(ducking)

I am with you on this one  bobw.

I'm somewhere around Papaw's thinking..........creates electrical current for something by hand?  The only application I can come up with for "something" is dynamite.

<silly smile on face> I know, I know - it's a hand powered welder :)

I would guess a bilge pump, except for the battery cable clamp.  Could it really be a bilge pump with the clamp for holding the pick-up end of the hose in the bottom of the bilge?

I'm going out on a limb here given Brit origin, and electrical design if the rod is threaded I'll bet on a carbon pile load device for testing batterys or individual cells.

Maybe it's for re-installing the smoke in Lucas wiring.

Impossible! Lucas can produce tons of smoke from the tiniest wire, no need to add it back in!

Well, yes, but when the smoke escapes, the wires get all clogged up and won't carry the electrons quite as well.
