Antiques roadshow

I've gotten tickets to an upcoming one of these, and besides a couple of items which fit their profile, am thinking of taking at least a small board or so to see what that does with their appraisers. anyone have any experience with them. This is the US mob. I'd never consider doing it with the UK ones. they want stuff from the 19th century or before, or WW2, etc. I am taking a sextant and a platinum broach. I have what I think is a Dec trainer board I'm going to take. i doubt taking any minis would be more interesting than the dec trainer. If they don't know that is a bit rare, then anything else they would say about other items would probably be useless. I'd like to see more scientific and computer, calculators, etc., on the show instead of the crap they sometimes have. Seems like everyone has a Tiffany lamp, or a bit of scrimshaw to show (fake and plastic, respectively). I was advised in an email that oddball stuff had shorter waits. Only guarantee is to get into the filming room where the appraisers are, and get stuff appraised. Will report back if there is anything useful that happens. Jim
