No verifier required???

I just got off the phone with the CFC. I had purchased 2 firearms from an online aution site and am going thru the legal transfer process. Anyway, the gal on the other end of the line told me that with the confirmation form I will be receiving, I will also be getting a form (which I apparently must sign & return) that verifies the make and the serial # of the firearms I purchased. I told her that I am not a government verifier, but she said that doesn't matter. Any input? Should I be signing anything like that?...I had received this form before and threw it out on another previous purchase, in fact I have since re-sold that gun and transferred it legally, with no comments or any problems with the CFC. What the hell is going on in BEAUREAUCRAT LAND? I tried searching out NFA Legal, but their site is down.Any comments will be greatly appreciated.
