This is for the fellow that was asking for info on spark plugs , sorry I cannot find the post again so will do it thus way . The club is : Spark Plug Collectors of America . Some , like other collectors , go at it in a big way . I have a friend that had to build an additional 5000 sq.ft. building to house his collection and you can hardly squeeze between the rows of plugs on display . It is unbelievable how many different types there are ! Good luck Stew. P.S. I can give you his Email if you need it .
