This is a Vintage Champion Spark Plug Firing Indicator or Spark Plug Tester. This item belonged to my father who was very knowledgeable about cars and enjoyed wokring on them. It may have belonged to my great uncle prior to that. I know very little about it other than what I have been able to research. I'll describe it to you as best I can.

It's vintage and looks like it was a popular tool. I am listing it as being from the 1950's, but I have no way of knowing for sure. It is certainly not in like new condition, but it looks good for the type of tool it is and having seen a good bit of use. I have no idea if it works. It looks like it is complete with a spring visible inside the clear plastic. It might still work. Please refer to the pictures I posted. I don't see any cracks, scrapes, or damage - it simply looks aged. The area around the clip could probably use some cleaning, but fearing I might clean it with the wrong product, I will leave that to the new owner.

This is sized similar to a bulky writing pen. It's 5 " long and about 1/2 - 3/4" wide. Clear plastic is over the lower portion with the Champion logo underneath. The clip has the most information. It is hard to read, but it says: Argus Mfg. Co. Chicago, Ill. U.S.A. On the other side it says Pat Feb 21, 1922. (Actually the P is mostly worn away on this particular item.)

I'm sure someone who collects automotive memorabilia witl love to have this in his (or her) collection. It could also be placed on a shelf for a decorative accent., or how about placing it in your pen and pencil holder at work where it will certainly bring comments.

This item will be sent to you in a box (not the original packaging.) Please read my shop policies.
