Found this is a junk box and had to have it but don't have any idea of age. Information might be available online but I am just learning to post photos in forums and figured I would try one here.

Looks like it's for the old style flathead sparkplugs. What size are the service ends?

 

[30-30remchester]

At tne widest one end is 1 5/16" x 1 1/4". At the narrowest it is 1 1/8" x 1".

I just Google "tungsten spark plug."

Tungsten Spark Plug - wrenchwiki

Tungsten spark plugs were manufactured by the Tungsten Manufacturing Company. The company was a division of the Marshall Oil Company of Mashalltown, Iowa.

They made at least two different sizes.
One about 6.75 OAL 7/8 x 1"
Other about 7.0 OAL 1" x 1~1/8
All sizes approximate.
Malleable iron wrenches can get a little out of shape from use.

Hard to believe they would get out of shape if used properly on spark plugs. Then again, I really shouldn’t be surprised at what so-called mechanics might do!

They may have made wrenches for other sizes
