USPS ?lost? my regulator

[LMN]

I had 2 first stages sent over for service. After service, they were sent back via USPS parcel. Package arrived after a 2 week delay with a torn corner, large enough to fit a first stage. The package was handed over to my wife by the driver of a van that did not have any official USPS marking. He mentioned to my wife that the package came ?like that? but ?everything is inside?. Sure thing, my Apeks first stage was not in the box. I want to give them the benefit of the doubt but somehow I have a feeling it was just stolen from the box.
I am attaching the pics of the first stage, just in case it pops up somewhere for sale and someone comes across it. It was sent to Atlanta from Panama City Beach.
Serial number 1012 4968




Thanks!
