Funny story sort of,
Thirty years ago, I was restoring a Parker Trojan 20 ga, but I had my gunsmith ship the receiver and barrels to Doug Turnbull he packaged the gun with the receiver in a separate box with Doug's address on it and then packaged the barrels and the receiver box in a shipping box. Week later I get a call from Doug and he asks "I thought you were shipping all the metal, I've got a receiver and a trigger guard what's going on?" Good question my gunsmith filled a claim and about 3 months later I get a call from Doug and he says you won't believe it, the barrels just showed up, just the barrels with a string tag with Doug's address on it, no box no nothing just barrels. I asked how bad are they, and he laughed and said considering all they went through. not bad at all, no dents some small nicks but no problem because we were planning on reblueing them anyway. So no packing at all and they arrived in one piece

Oh they were found in UPS's warehouse in Atlanta which is where lost goods go to. If I hadn't raised an uproar and pestered them with weekly phone calls probably never would have found them. So sometimes you just never know
