Original Rubber Spark Plug Protector hygiene The last three photos areOriginal German Isolator zundei or spark egg. It is a rubber case to protect spare spark plugs and keep them ready for use. Price is for one holder; spark plug is NOT included! These are absolutely indispensable for original vehicles. They are a little dirty, but still in decent, usable shape. These are difficult to come by in good condition. They are advertised in the 1931 Stukenbrok Hauptkatalog.
