It’s okay, this 70-year-old Firestone T-30 spark plug is no longer radioactive and is perfectly safe to own and handle. The Polonium 210 used in the electrode was supposed to improve its performance (apparently it didn’t…) and it had a short ‘half life’ of just 139 days, which means that three years after it was made it had all disappeared and turned into non-radioactive lead.

 It was manufactured in the USA by Firestone in 1945 and is one of a very small quantity that was recently discovered in an auto parts store. They have never been used and come with their original cardboard box. These have been carefully mounted inside a custom-made glass-fronted, wooden display case (15.7 x 20.7 x 4.5cm -- size and finish may vary slightly) along with a reproduction of an original Firestone information leaflet as a backdrop. The cardboard box and plug are both in excellent condition, they have not been damaged in any way and could be removed from the case and used for its intended purpose (the T30 fits some late 40’s Chevys) should you so desire.

 

Once our small stock has been sold there will be no more so don’t miss this incredibly rare opportunity to own a piece of automotive history and WW II memorabilia, with macabre contemporary overtones.
