Now that 18 months have passed since the question was submitted to BATFE, I'm wondering whether they have gotten around to responding, and if yes, what did they say? I'm sure this wasn't the first time the question has come up and further would guess they have a standard response prepared. It's too late now, but if it had been me, I think I would have re-stamped the SN without even asking and just said it had apparently gotten weak and hard to see in polishing and I had just "reestablished it." If anybody noticed it at all, which is pretty unlikely, that should suffice. This is not legal advice, but is based what I've seen done. It's probably some sort of technical violation, but I would plead "good faith" and unless they were trying to get me on anything they could drag up, I doubt they'd pursue it.
