I've likely said this here before, but the only time I ever shipped a gun by USPS Registered was when another member here and I were trying to work out a Lefever swap. The guns were both pre-1898 so the shipping was person to person.

We decided against the exchange after viewing each other's Lefevers and I decided to ship his gun back by Registered mail for safety. The returned gun going to Cincinnati I believe, went missing. After several weeks and an unproductive trace the gun showed up at the other party's office.

It turned out that the gun was last signed for by a postal employee in Cincinnati who'd gone on her two week vacation, leaving the package in a locker. It took another two weeks for the post office to get around to delivering it...Geo
