Nice talking with you also Terry and will drop by at Hershey for a visit. Also thanks for the info posted above.
Anyway the start of a collection seeing I have more than three items if that is the general consensus rule. Using an Alumite display box I am thinking from the teens that I bought somewhere in NY state years ago. Made of wood then wrapped in tin.
I will have to search the barn as I am sure I have a couple of tin boxes full of old spark plugs I bought at auction again years ago.
What do people collect in plugs like everything, a brand, country of origin or oddball??
