In the none to distant past, I received a similar letter from the BATFE. It accused me of a felony. Several felonies, actually. As an FFL holder and owner of several NFA items, this was rather alarming. My only immediately comforting thought is that these letters usually arrive with 15 to 20 Federal agents, each armed to the tooth. My letter was delivered by the postman. I couldn't reach anyone at the ATF on the phone for several hours. After a good bit of sleuthing and google-fu-ing, as well as emailing everyone in the ATF chain of command that I could find, I finally reached an agent who knew exactly what was going on. He apologized profusely. I was not under suspicion of anything. It was a fishing expedition that cast a very wide net. So wide that the response had shut down the phones and email at the bureau. I eventually got a letter of clarification from the BATFE, a verbal apology, and a verbal promise that it wouldn't happen again.
Now, I think that I will go place an Esterval's order, just to poke the bear.
