Each Spark Plug Snowmobile is a little different from the next. It all depends what salvaged metals parts i can get a hold of. Made with a spark plug, bike chain, nails and sheet metal all hand cut and bent into shape. They are cleaned and have a clear coat applied to keep from rusting. I usually have several on hand and am happy to provide pictures to pick from. Great for a desktop piece. The Rusty Bolt Creation are assembled and welded with salvaged metals.
