This is an original 1974 comprehensive trade catalogue from the Champion Spark Plug Company. This 200+ page shop manual was the primary reference tool for automotive workshops and dealerships during the mid-70s. It features exhaustive application charts and cross-reference listings for spark plugs and tune-up components across a massive range of machinery—including General Motors passenger cars, trucks, marine engines, and garden tractors.

Manufacturer: Champion Spark Plug Company

Condition: Used (Vintage workshop condition; features original index tabs and factory hole-punching for binder use; see pictures for true condition)

Model Number: Form No. A-74 (Standard 1974 Issue)

Extra Notes: 1974 was a significant year in automotive history due to the transition toward unleaded fuels and early electronic ignitions; this catalogue captures that shift in real-time. The inclusion of specialty sections for garden tractors and small engines makes it highly desirable for collectors of vintage John Deere, International Harvester (Cub Cadet), or Massey Ferguson equipment who need period-correct part numbers.
