I would second what Mr. Vicknair is saying. Go direct & ask. I've not done that recently, but I have done it and was treated w/courtesy and given the correct information I needed at the time.

In the course of this discussion I would also mention that most times a gun is being worked on it is logged into something, so there is another place a record is being kept w/the serial number and owner's data. I do not know if that is because a gunsmith is an FFL holder or some other law coming into effect or no law at all aside from sound business practice. Its not an issue I am concerned about; that practice was going on well before the GCA of '68.
