Different Spark Plug

[Larry Schramm]

I picked this spark plug up over the weekend at a swap meet because it was different.

 

Any ideas on the application.  My guess is that it is for a hit & miss engine.

 

Thanks

I think we have a winner. Here's a similar spark plug for a kerosene heater.

I am always impressed by the vast knowledge of the forum group.

Is that a Champion 589 plug?  If it is, that is the sparkplug that I use in my Buicks.  If not a 589, then do you know the plug number?

I did a short contract engineering job in a lead foundry a very long time ago and they had some really unique spark plugs for the gas burners under the crucible - many with very long electrodes to get well out of the heat.

It's a HA3012 plug for a Reddy Heater. Sorry, I don't have more info.
