[Eighty]

Hey all, I have found a box of (30) FLINT, take a part, 7/8 base spark plugs. they are still in the original boxes and wrapped with waxed paper. The boxes are marked FLINT spark plugs, aero, Jackson Michigan. Do any of you know anything about these? All have never been used, brand new old stock!!!
Thanks in advance, eighty
