This may be more of a applications question than a tool question. My grandfather had 9/16 deep socket marked for spark plugs only. I also read on ths site that there were spark plug sockets 9/16 to 1 inch in 1941 . Does anyone have any idea what cars tool such a wide range of spark plugs? Thank you

I have a couple of those. I never looked up what they fit.. They are hard to find.

Electricity wasn't everywhere and there were stationary engines doing the work. Along with agricultural and industrial equipment. Maytag built a washing machine with a spark plug and kick start.

I have a 7/8" S-9803-B spark plug socket that is included in 1939, 1941, 1946 and 1948 catalogs. this socket was made for the Buick AC-86 Blue-Top spark plug.

Interesting that the "N" is backwards.
