Has anybody got any info on this?

I wondered if anyone could tell me anything about this? I just picked it up cause I thought it looked cool. I have no information about it other than what it says on the front.
It says "R.F. JAYNES Battery Inspector"

 

Looks like a small rectifier used for plating. Does it have a 110 coard on it

 

Maybe an old batttery charger... Dont trust me on that im only 13

 

It's a radio from a WW2 German PanzKampfWagon 4.

 

After consulting my crystal ball AND the label on the front, I would say that it is a battery tester..........

Look's like they have been around for a while!

I agree. Looks like a battery tester. Does it have heating coils inside like a toaster or hair drier to put a load on the battery?

 

Here are a couple pics inside.
I am curious as to the age of this thing and how common(or not) they were at the time.

 

looks like a robots head

 

I never thought of it like that. That's very amusing.

 

Most garages had something like that, and you can still buy the modren equivlant. HF sells one that works the same. In the one pic you can see the carbon plates that provided the load. SUN equip made a lots of them,I've had several.

 

They must have left it behind when they bombed Pearl Harbor.

 

I'll try to get some better pics. I'm still experimenting with my new camera.

 

Them dang Gemanize

 

First pic is the carbon pile , that was mentioned before. The second pic is the current shunt. The Shunt is a precision high current low resistance resistor that measures voltage drop. A low voltage meter calibrated in amps read out current. Most testers like this are called VAT's Volt, Amp Testers. Nice old tester you have.

 

Thanks. I thought it would, if nothing else, make a cool garage ornament.

 

If it's built like most of that old timey electrical equipment, you can still use it and probably for another 50 years

 

If you want to sell it, I'm interested.

 

I don't really want to sell it at the moment. I'll keep keep you in mind though if I ever decide to sell.

 

The Germans didn't bomb Pearl Harbor, the Japanese did. ...And it does look like a robots head! Ha-ha!

 

Huh? ...the Germans bombed Pearl Harbor? ...and all these years I thought it was the Japanese.

 

I wouldnt know what it is but i'd keep it as a garage piece for sure.I have a couple of oddball instruments from the 60 that i gathered from the skip at work and im constantly lookin for kool pieces like this one to put on my garage shelves togheter w/ my very few speed parts and accssories.Nice find, just buff it a little and youre good.
