I jsut looked them up on the Write banding webite. Which is reportband.gov. There was no listing for them! Although, they only go back 20 years in their listings on the site. So if they are older than 20 years old, which I am thinknig they are, they could be worht some jack! I would get on the site and get the number and call them and see what they have to say! Any real AVISE bands are worth some cash if they are legit!
