Re: 1952/1953 Spark plugs
In addition, Bosch spark plug insulator design changed over the course of the 1950s. The early ones were not ribbed, and the green stripes were dark green and depending on year, had different thicknesses. The 1950s spark plugs have Bosch date code letters stamped into them for the year. So H for 1952 and J for 1953.
In the photo below, "P" 1958 on the left, "J" 1953 on the right.
