Hi Paul,It has a star shaped wheel inside and a condenser. It was used to test coils without points. It is the interrupter. You connected it to the battery and in series with the ignition coil and ran the HT lead back to one binding post and from there it jumped the gap so you could see how the coil was working.
The knob on top is the on/ off switch. Frank At 01:17 PM 8/24/2014, you wrote:
I collect old induction coils, etc., so I watch for them on eBay, naturally. This item showed up: http://www.ebay.com/itm/390905035563?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 What is it? Itâ??s cased like an old spark coil, but the connections and hand crank make me think it must be some kind of magneto, maybe for an old telephone? What do you all think it is?
