    A few of my sparkplugs to show you.
    Pic #1... there are six primer plugs in this photo. The plug in the center with the arm extending out to the left is a quick detachable plug. The owner would keep several "stingers" in the glove box, and when the plug fouled (as they often did in early autos), you turn the bayonet arm 90 deg. and pull out the dirty stinger and replace with a clean one. You can then go about your way without getting your clothing dirty.
    Pic #2.... The plug in the center is a "Champion Harley Davidson" racing plug. You can also see the QD plug (quick detachable), to the left of the Harley Davidson plug.
    Pic #3...(center of photo) shows a plug that, when fouled, you just flip the plug around to expose a clean plug
    Pic #4... shows a number of fiber insulated plugs as well as a Splitdorf and Bethlehem plug along the bottom.
    Last year, I had an auction with several hundred rare plugs for sale in tray lots of five to ten plugs offered by choice of each tray. To give you an example as to how desirable sparkplugs can be. One tray of five rare plugs, sold for a pick it out by the piece for $750 each, and the buyer took all five plugs on the tray.

      Hey, that was quick !! LOL !! Great collection. What are the ones with valves on them. Some sort of compression release ?
    2. hotairfan hotairfan, 4 years ago
      the valve sparkplugs are primer plugs. Some engines used this valved plug to prime the cylinder with gasoline for easier starting. With the valve closed, full compression in the cylinder could be reached.
      Two of the plugs shown have the valve on the top of the plug. (pic#1.. top and to the right). and pic#3.. shows a top primer with a little "L" shaped screw opener. These top primer plugs are hard to come by.

      Fascinating. Interesting looking at the different coil lead terminal shapes and the different electrode shapes and protrusions.
      You have amazing collections hotairfan.

    6. blunderbuss2 blunderbuss2, 4 years ago
      I've spent some time studying your collection. 1st question is about the lower rt. plug in pic #1 ?
    7. kerry10456 kerry10456, 4 years ago
      I have several of the Harley Plugs, still in the original boxes, I got them from a old board track racer, back in the 1970's and he was really old then, lol
    8. kerry10456 kerry10456, 4 years ago
      Should also add, these plugs were standard for the WLR 45 cubic inch flatheads
    9. hotairfan hotairfan, 4 years ago
      thank you for all of your kind comments. To blunderbuss2 .... the plug located in the lower right hand corner of pic #1 is a Mosler Spit-Fire plug pat. 1902

      Very nice collection:)

      Hi hotairfan , I to have a collection of spark plugs some 2400 that is a very nice collection . Priming cock spark plugs are very hard to find in New Zealand as with a lot of the Rarer plugs are . Most of mine now come out of Europe or the States..
    13. blunderbuss2 blunderbuss2, 4 years ago
      Hotair, if your vehicle keeps fouling out plugs at this rate, maybe you should get a ring job !
    14. ralph ralph, 4 years ago
      I have one like the green one and I would like know moor about it can anyone help.
    15. hotairfan hotairfan, 4 years ago
      Hi bb, these plugs were often used in early model T's, or autos of that vintage. They were notorious for fouling at the drop of a hat if you used poor or stale gasoline.
    16. hotairfan hotairfan, 4 years ago
      Hi ralph, the green sparkplug is a Splitdorf brand sparkplug
      In the first photo, there is a Splitdorf primer plug.
      In the 4th photo there is a Splitdorf with 1/2" pipe threads. The 1/2" thd. plugs were often used in Ford model "T".

      Okay I guess it's true, there's a collector for everything, lol. Nice collection! :)

      Karen, I had no idea you knew stuff about cars! Come and fix mine! :))

      Hi fuzzmugin, I sure would love to see your collection. You mentioned that you have a lot of plugs from Europe, I have an interesting plug, called a "Make & Break" spark plug. It is made by Bosh, and it is one of the neatest plugs in my collection. I will try to post it today, check it out.
    19. fuzzmugin fuzzmugin, 4 years ago
      Hi hotairfan will start putting on some of my displays now that Salmon fishing is coming to a close.. We very seldom if ever find the coil plugs in NZ the Bosh one would be a dream plug in NZ...
