Default well, how did i do...sparkplug buy

I went to a car swap meet and left with about 40 old sparkplus...Auburn 18-H (four)...AC TITAN (pat'd Mar. 12 1915)...firestone Polonium M-80-F. Champion UJ-12 Y with some sort of extension that it threded in to and then that extension into the cylinder head (WHAT IS IT?). Champion X with out any ribs on the insulator. Champion X with ribs (Actualy about five with ribs...most of them are missing the threaded bit on top, cracked off) Champion 15 A...Champion 1 com. champion 2. champion 3 com. champion C-4.... "Imperial" (no other markeings)...a un marked plug with a green band around the insulator and no ribs...and a bunch of other plugs...I am thinking of brazing brass screws to the champ. X plugs that lost there heads. all of these for $5, so how did I do?

Yes the spark plug used to be radioactive. But it had a very short half life. I think like 138 days. It used to be quite radioactive. Polonium is still used in the photographic industry on brushes to remove photographic film.

We have one as well, with the box and everthing. Purple colored.

According to my calcalations, assuming ~3 half lives/year times 50 year old spark plug you got 1 over 1 followed by 45 zeros of the original amount left ! I had always wondered about polonium- didn't realize the half life was 138 days.
