1943 B G Type Sparkplugs

[Dean (Ajax)]

I am heading off to the Sataes for a few days and was going through my garage looking for a few things to take.

I came across a box of 10, 1943 Dated Sparkplugs...they are still in the carton and are each in a tube.

The Box end has a lable that states "10 Spark Plugs B G Type LS 321-A

Any Ideas what they fit

Thanks
