Further to my earlier contention in this thread that Iron Barrel Bullets may be able to communicate with their fettlers, submitted for your consideration (cue Twilight Zone theme music), I offer the following evidence discovered in a recent video by our very own "Bullet Whisperer", Mr. Paul Henshaw, at: https://youtu.be/KoMbxPI4ppI.
Towards the conclusion, from about 22:50 into the film, he explains how the new toolbox lid had shaken open during the ride, during which he had noticed some charging issues and difficulty restarting after a planned en route stop to check for oil leaks. He soon goes on to explain the actually fortuitous nature of that side case opening on its own like that, since it reminded him of a fuse within that he had bypassed temporarily to perform some electrical work, but which he had forgotten about. That missing fuse, was, of course the cause of the charging issues and difficulty starting. Was the case opening on its own like that merely "luck" or "chance" or something else...in the Twilight Zone. You must decide for yourselves. For me, my comment left for that video sums up my thoughts best:
Regarding the toolbox just "randomly" popping open like that, thereby reminding you about that fuse bodge you'd forgotten: Don't you find it a tad weird it just doing that? I mean, flipping open the damned case? Really?! C'mon! That's some Chitty-Chitty Bang-Bang grade antics there! I've said it before, and felt odd doing so, but I tell you those "Iron Belly" Bullets got a SOUL! If you but listen, they'll let you know what they want and need. Clearly in this Bullet's case it'll even reach out and rap you on the kneecap if you mess with it. Next it'll be crank calls in the middle of the night...
(Ringggg!...Ringggg!)
"Hello."
"My plug...It's dirty."
"Ummm...Who is this?"
"VERY dirty...You should SEE my dirty plug."
"Seriously, who IS this?"
"You know who this is, Paul. You've always known."
