That’s substantial growth from new (.039”/1mm) after only ~77,500 miles.
My M112’s OE NGK IFR6D10's gap had increased a scant .002”-.004” by 50,000.
Serves as testament to the strength of our ignition system that you weren’t suffering misfires.
During the leaded fuel and pre-platinum/iridium plug era, .001” erosion per 1000 miles was considered normal. The Charles Kettering-style points and condenser were hard pressed to bridge the ever-increasing gap. Even fitting a Bosch ‘blue’ coil to a former Karmann Ghia did little to extend the NGK BP6ES’ useful service life.
Owing to documented air quality and fuel consumption improvement from doing so,
my trusty MSD 6-equipped GMC receives a fresh set of 99¢ AC CR43s annually.

yup not a single missfire started up fine till this winter it needed a few cranks (3-5 engine cranks before it started where before it was 1 or 2)

It's a 1946 Jeep! - Are you actually adding lead or a lead replacement additive? Probably a lead replacement additive. Raw TEL & TML are awful substances especially neat & need to be handled with due care.

lead replacement additive
i really dont have much risk burning out the valve seats with my huge 4 cylinder 60hp engine
so i only add it every few tanks I only put about 200 miles a year on it as a top speed of 60mph no turn signals or seatbelts and a single brake light make city driving a pain

Guess I should pull out the records and see if I've ever replaced plugs. I don't remember doing it, and at 141,500 now, I might want to think about it...
But then again...
