Sir, if the Skeuse family surrendered their records to ATF, we will never see them. We don't know whether their manufacturer's license is still active and I don't expect them to tell you about that either. "There are no more 0000 frame .410s left." sounds like a stock answer. I believe what you call the "trace center" is in West Virginia. Since you live right across the state line, why not run on over and knock on the door? I've been there and it is a friendly little place.
